Evo ovaj frajer je 2018 bez interneta napravio btc transakciju.

Isto kao i bankovne transakcije i stanja na računu, koji 99% nisu papirnati novac ili papirnati dokumenti, nego baza podataka negdje na serveru.

Za oni koji malo bolje prate tržište kriptovaluta, šta mislite o PI kriptovaluti i predviđanja hoće li imati ikakvu vrijednost u budućnosti?

Nisam nikad cuo za taj coin, ako si novi u kripto svijetu drzi se Top 10 projekata, sve ostalo je za pocetnike opasno + ako coin ima hrpu placenih reklama to je veca mogusnost da je scam, bjezi od njega i ne okreci se, dobri projekti netrebaju placene reklame.

Jel istina da uz svaki Bitcoin dolaze informacije o apsolutno svim transakcijama (tog istog Bitcoin-a) kroz čitavu njegovu povijest ?

To ide kriptirano preko Internet mreže. Osim nekih situacija kad koriste satelitske telefone. Mislm bar, nisam dublje ulazio u to.

Kao posljedica rudarenja odoše cijene grafičkih kartica za računala u nebesa.
Skoro 90% novih gpu-a se kupe u svrhu rudarenja, opća nestašica na tržištu a cijene luduju.

Prednost bitcoina je da mos imat nekoliko vrsta novcanika i racuna. Mozes imat kod doslovno na papiru. Onda ga cuvas u fizickom obliku. Ako ti ga netko ukrade racunaj da si 'hakiran'

Novcanik ti moze biti:
Fizicki digitalni na posebnom ledger USB sticku
Fizicki papirnati
Mobilni ili PC app
Racun na mjenjacnici poput binance ili crypto.com
Racun na banci jer sad mos na bankama drzat tako


Kako te volja, najlakse instaliras atomic wallet i tjt.

Priko mjenjacnica uzivo, mjenjacnica online, kripto bankomata, uzivo sidnes sa nekin na kavu on tebi doveze auto ti njemu na racun btc on tebi kljuceve i potpise i tjt, imas brojne mogucnosti koje onemogucuju prevare tim putem, to se zove smart contracts.

Neke zemlje koje imaju financijski inovativno vodstvo poput Slovenije, mozes i kupovat u vecini ducana s kriptom. Evo i benzinske crpke uvode placanje btc.

Ne. Pogotovo ako ti je btc fizicki na mobu, u ledger USBu ili na komadu papira. Ako ti je na binance racunu onda ti mozda netko otkrije sifru no isto ti je sa bankovnim racunima itd. Za bankovni racun imas osobu imenom i prezimenom koja ti stoji ko posrednik i nerijetko ti skidaju s racuna par posto svima.

Bilo je hakerskih napada na mjenjacnice kriptovaluta no ne moras drzat tamo kripto. Samo ga posaljes samom sebi na USB. Atak na samu strukturu btc koja se zove blockchain je neizvediv.

Ne. Btc struktura je na blockchainu i on je na svakom uredaju koji sudjeluje u btc. BTC moze biti unisten jedino ako SAD i Rusija zapocnu nuklearni rat no u tom slucaju te nije briga ni di ti je hrana kamoli di ti je btc racun. Doduse cak i onda ce ostat na laptopu ili mobitelu na Islandu ili Antartici i u serverima koji su u bunkerima. Al nebitno. Taj scenarij zaboravi.


Vicevi su specifican tip zabavljanja. Zahtjeva jednu orjentiranost prema meduljudskoj osjetljivosti, citanju govora tila, emocija i umjece naglasavanja itd. Ti imas dosta oprezan i pomalo cinican stav prema ljudima. Indikacija da drzis distancu i da to nije tvoja domena. No da, ja znam procjenit ljude i nisi ti tupast. Imas ti IQ bar 115, vjv malo vise.

To ti dolazi uz adresu. Ako netko sazna tvoju adresu može vidjeti tvoj promet BTC-om od početka.

Zato se za BTC i naglašava da je pseudoanoniman.

Adresa mozes imati stotine.

Pa da, ali ako netko sazna jednu od tih tvojih adresa sazna čitavu prošlost tvojih transakcija s tom adresom.

Nisam to pitao
Mislim da je ta valuta neodrživa stvar, posebno ako bi postala primaran način plaćanja. Silan hardware treba samo da bi se spriječilo izmišljanje digitalnih coins i prevare. Od prvog dana uz svaki Coin ide čitava povijest kuda je išao i kako.

Zamisli da uz papirne Kune sa sobom u torbi moraš nositi papire i podatke gdje je ta Kuna krenula prvo i sve do danas, da neko ne bi krivotvorio tu istu Kunu i pustio je u opticaj. Mislim usporedba i nije OK a i je. Infrastruktura ne može podržati crypto valutu u budućnosti.

Digitalne valute pod kontrolom država su sasvim druga stvar.
Ne govorim šta je bolje, normalno da mi se crypto valute više sviđaju ali samo primjećujem.

Bitcoin radi još uvijek na original softveru kakav je bio 2009, problem je broj sudionika koji je narastao na preko 100 milijuna kao i veliki broj transakcija.

Satoshi je tada iz sigurnosnih razloga uveo ograničenje veličine bloka na 1 MB kako bi spriječio DOS napade hakera koji bi mogli sa velikim blokovima paralizirati mrežu.

U međuvremenu neki developeri nisu bili zadovoljni sa tom odlukom pa su napravili hardfork kao BCH i promijenili maksimalnu veličinu bloka ja mislim na 32MB što automatski
znači veći broj transakcija po sekundi.

Bilo je mnogo prijedloga za skaliranje, aktualni prijedlozi su segwit i lightning network, ali niti jedan do danas nije implementiran.

Zato btc u ovakvom stanju kakav je sad (bez second layera) ne može služiti kao platežno sredstvo u svakodnevnom životu, jedino kao digitalno zlato.

A u slučaju da second layer nekad u budućnosti bude gotov onda će platežne transakcije biti moguće jer će se odvijati na nivou iznad blockchain-a.

Token burning: What is it and what are the benefits?


https://swissborg.com/blog/token-burnin ... 20use%20it.

While burning a financial asset might sound extreme, burning crypto tokens is a fairly common event.

Token burning is a strategy followed by cryptocurrency projects to influence the price of a token, or coin, in the market. This is done by permanently removing some tokens from circulation. While the major cryptos (Bitcoin and Ethereum) don’t have token burning programs, many strong Altcoins use it.

For instance, Binance has a target of burning 100 million BNB tokens, while there are similar practises for both USDT Tokens (issued by Tether) and XRP coins (issued by Ripple).

How does token burning work?
The goal of token burning is to remove a certain quantity of a token from the circulating supply.

One of the most popular ways crypto projects carry out a burn is to buy a certain amount of tokens from the market to get it out of circulation. These tokens are then transferred into a frozen private address called a Burn address. It’s a one-way address with no ability to reverse the transaction or withdraw the coins - the burn address to which the tokens are sent can never be recovered because there is no private key corresponding to that address. For all practical purposes, the asset no longer exists - it has been “burned”.

A good example is the Binance Quarterly Burns, with the most recent one happening in July 2020. The company has burnt around $60 million in BNB tokens since the inception of the Quarterly burns.

Ripple, a top digital asset, also does this but uses a different method. It reduces the number of transactions allowed on its network, limiting the possibility of a DDoS attack (which disrupts the normal traffic of a service, server or network). Another way is by taking the fees used as “gas” to make a transaction happen faster than usual. This reduces the supply of XRP circulating in the market on every transaction done.

Stellar, another cryptocurrency company, proceeded with a token burn of 55 Billion of XLM to increase the coin’s value. This burn effectively reduced XLM supply by over 50%. The price effect on XLM was quickly noticeable in the short term, moving from $0.069 to $0.088 in a day (around 25% from November 5th to November 6th).

Even stablecoins like USDT, GUSC, USDC and HUSD have conducted burns of over $2.8 billion. This provides transparency of the reserves once funds are added or retired. When there is a deposit in reserves, tokens are minted. The burning happens when the coins minted into the reserve are withdrawn, regulating the circulating supply and keeping the balance stable.

What are the benefits of token burning?
There are several benefits of token burns.

The most well-known benefit is that token burns may result in the value of the coin increasing. The XLM example mentioned above is a good reference. The corresponding increase in the value of each XLM unit demonstrates that token burns impact the price of a coin, at least in the short term. Like many tokens, however, XLM fell during the Coronavirus crash, but since late April 2020 the token stabilised, reaching the $0.10 mark in July of the same year.

In the case of XRP. The constant burning keeps a steady value of the token and also bets for a long term price rise. Using metrics from the same period and considering the same crash factor, the price has remained around $0.28 to $0.31 from November 2019 to August 2020.

From the community angle, you could argue that token burns are a form of airdrop due to the value of community holders’ tokens increasing. For example, Project X conducts a token burn. Afterwards, the supply reduces and the value of the token appreciates by 10%. Accordingly, this has made every community holder’s token more valuable than it was before the burn. Hence, Mr Y who holds 1,000 units of Project X tokens would have had the value of his holdings appreciated by 10%, even though he still holds his original 1,000 units. In essence, Project X just did an airdrop to every token X holder who didn’t need to spend a dime to increase the value of their holdings. Perhaps, this is one of the reasons community members are endeared to projects that announce they will conduct periodic token burns. Many projects even employ this as one of their marketing tactics.

Trust and confidence in the project is a key element. This is where, for example, during the ICO stage, it is common to find the burning process is done once the token or coin is finally launched to provide the new investors with the reliability that their fund will not be affected by an over circulation.

Additionally, by reducing the circulating supply of a portion of the circulation of a cryptocurrency like the XRP example we discussed above, the number of transactions gets equally reduced. In a nutshell, a reduction in volume lowers the chances of spam attack which leaves enough bandwidth for health transaction count on the network.
