Can we rely on a market 51 attack cost hash power continuing to not best mining 2019

51 attack cost

This is essentially relying on large miners being unwilling to rent out their mining capacity. Altcoins are more at risk in this respect, because it is easier to acquire the amount of hash power needed to attack an altcoin.

The second big assumption is that the exchange 51 attack cost permit an untrustworthy attacker to quickly 51 attack cost a large amount of currency.
