Kryptoměny: Bitcoin, Litecoin a ti druzí

Notes

Například Litecoin, označovaný jako stříbro k bitcoinovému zlatu, se těží na podobných specializovaných zařízeních s obměněným algoritmem těžby, má 4× rychlejší potvrzování transakcí a 4× více mincí. Jinak je Bitcoinu velmi podobný. Zcash, Monero a Dash jsou kryptoměny specializující se na skutečnou anonymitu transakcí, které se u kryptoměn kvůli jejich transparentnímu charakteru dosahuje obtížně.

Novým fenoménem minulého roku se stalo vytváření kryptoměn pomocí tzv. forků neboli rozštěpení. Jako první tímto způsobem vznikla a udržela se kryptoměna Bitcoin Cash, současný rival Bitcoinu, od kterého se odlišuje jiným způsobem řešení problému navyšování transakční kapacity.

za každou transakci v rozmezí 0,3–300 Kč moc na malé nákupy a převody nehodil, a proto doporučuji začít experimentovat s litecoinem, který je bitcoinu velmi podobný, je dostatečně rozšířený, ale poplatky má stabilně nízké (pozn. V současnosti jsou bitcoinové poplatky opět velmi nízké a lze posílat transakce s poplatkem menším než 1 Kč, nicméně ještě v únoru dosahovaly v přepočtu i 100 Kč a předtím v prosinci dokonce přes 300 Kč. Přesto doporučuji začít litecoinem, a to z cvičných důvodů).

základem k bitcoinu jsou podle mě další dvě kryptoměny – litecoin a monero. Více na: https://www.euro.cz/kryptomeny/do-jakych-kryptomen-investovat-bitcoin-litecoin-monero-1457597#utm_medium=selfpromo&utm_source=euro&utm_campaign=copylink

od kterého to teda má ty adresy rozdávat. Paráda. Díky moc.
