Bitcoin SV (BSV) Suffered A 51 Percent Attack! It can be defined as an invasion on the blockchain caused by malicious miners taking over more than half of the network's processing power. Once these attackers have taken over the network, they can prevent transactions on the network from being approved, thereby stopping payments between users. In addition, attackers can spend twice with the coins in the network. BSV is the 44th largest cryptocurrency in the world, with a market value of $2.6 billion. BSV was created as a result of a hard fork of Bitcoin Cash in November 2018. Similarly, Bitcoin Cash was created in 2017 as a result of Bitcoin's radical protocol change.
