#BTC coins with no or no history of transactions are commonly referred to as "pure" bitcoin.
The #blockchain of the first cryptocurrency is designed in such a way that it is possible to trace previous transactions of a particular coin and establish whether or not it has been used for illegal transactions. This is difficult to do for the average buyer, but quite possible for a large service, such as a cryptocurrency exchange.
Therefore, when #buying bitcoin, there is a risk that a particular BTC was previously stolen by hackers, caught on the darknet or in other illegal transactions. Such coins are flagged and there may be difficulty selling them in the future. The exchange will refuse to accept a deposit, block funds or law enforcement will insist on confiscation. This issue is especially relevant given the regulations proposed by the FATF, which require that the personal data of the sender and recipient be attached to each #transaction#transaction
To avoid such #risks , large investors prefer to buy bitcoins without transaction history, which were mined by miners and stored in their wallets. Such BTCs are called "pure", and their price is 20-30% higher than the market price.
