Well, mate, you got a point. Mining and staking do both call for some dough. Decentralization is indeed tied to how the capital's spread around.
But let's not forget: Bitcoin was made to be permissionless. Anyone should be able to join in without needing a stash of coins first. Staking kinda puts up an entry barrier, ya know?
I won't argue that eCash has taken an interesting route with Avalanche + Nakamoto consensus. Each chain has its own strengths and weaknesses depending on what it aims for.
Bitcoin might not replace cash entirely given its properties but it sure does have other perks like being digital gold or a store of value.
Always good to see different chains trying out new things though! Keeps the space exciting! #Bitcoin #eCash #Decred
