Ethereum Services Are Centralized
This will likely be controversial, but tech like bitcoin is a big step backwards from payment systems we currently have.All the rules and regulations were created because someone was bad enough for people to agree on a rule to prevent something from happening again.Block chain money loses all of those protections to stop a bad actor from, say, a hacker draining your wallet with no recourse.So we find ourselves back to step one. I do think it's inevitable layers of regulations and rules will crop up, either from governments, or power holders requiring layers of smart contracts to respect transactions.It will just be a matter of time till the modern banking systems "port" themselves onto the chain.
