- Non-segwit transactions require 51% of the hashpower and a private key to steal. Segwit transactions just require 51% of the hashpower.
You statement is very confusing since you are taking about two things: a) 51% attack and b) stealing coins.
How can you steal coins without private keys on Bitcoin? What kind of bull shit is this?
Please enlighten me!
You haven't been listening. A 51% miner gets to declare that what were formerly segwit transactions are now anyonecanspend transactions. After all, that would merely be reversion to the consensus rules that existed before segwit activation (by a so-called 'compatible soft fork'). What happens to an anyonecanspend transaction? It's output is literally assignable to anyone. If you are mining, you are you going to assign that value to other than yourself? If you solve the block, they're yours.
Funny thing however, is that it is arguably not stealing, as it is merely operating under the existing consensus rules. Ones that were universal before some misguided individuals promulgated the idea that they were something other than anyonecanspend.
