Speaking of actions and words, what good is a contract if it can't be enforced? So I find hard to trust Ethereum.

All that new stuff could change the point of view if it were some ordinary software, but since we're talking about a currency, trust is very hard to regain. How can someone be sure that they won't change their mind again?

I haven't followed the evolution of Dogecoin, but even that sounds more reliable and at least it doesn't pretend to be taken seriously.
