Vitalik Buterin is concerned about Bitcoin’s security!


In the interview with Noah Smith, the Ethereum founder pointed out two reasons why he is concerned about the security of Bitcoin in the future.

“First, in the long term, Bitcoin security is going to come entirely from fees, and Bitcoin is just not succeeding at getting the level of fee revenue required to secure what could be a multi-trillion-dollar system. ” Buterin wrote.

Second, proof of work provides much less security per dollar spent on transaction fees than proof of stake, and Bitcoin migrating away from proof of work seems to be politically infeasible Says Vitalik
