Thank you all for the follow up.
I'm going to answer to some of you.
ABCbits - "Mere copies? Ridiculous, many sidechain/L2 offer feature what Bitcoin doesn't."
That's not what I said, the "current system" I'm referring in that specific quote is the FIAT system.
I see. But your thread doesn't mention fiat, bank or government, so how would i know you refer to fiat system? Besides, only some sidechain/L2 are centralized or federated with only few members.
