Cryptocurrency transactions are recorded on a decentralized ledger. This ledger is called a blockchain. Every time crypto is bought or sold, the transaction is added to the blockchain — a public database of the transactions, which is available to other crypto holders. Anyone can join and participate in the blockchain, but data on individual transactions — and the people involved with them — are secured using cryptography (the basis for the term cryptocurrency). For each transaction added to the blockchain, there’s a digital validation process to verify it and prevent fraud.
It will impose a 10 percent penalty tax fee on sellers and redistribute five percent of this tax to other people who already own the cryptocurrency.

But of course you'll want to be wary of another possible Squid Game fiasco, which reportedly scammed users of an estimated $3.38million.
But that doesn’t mean it’s completely secure in the same way most people consider the U.S. dollar or other established currencies to be secure. Since cryptocurrency isn’t backed by any governmental authority, it doesn’t have the same protections as many standard currencies throughout the world.
