Certainly feasible.
Oh Canada might be leading the pack, hats off to that.

But other smaller countries, more progressive places....Sweden, Germany, Iceland, etc, will get on board.
Anyone who just studies economics for more than 2 hours (I believe) would realize that our current world finance system is really messed up, has lost a link to reality due to fiat currencies being leveraged one-dollar-to-a-hundred to by banks, and currency that has a backing, whether it is gold or enforced digital scarcity via something like Bitcoin's design, is just a more logical, superior way to hold value somewhere as opposed to money you printing up by the spare 100 billion that gets given to the banking cartels on the regular to keep running.
Or current financial system just does not add up. You needn't look any further than many of the world's supposedly richest nations looking at going bankrupt if they weren't able to print up money from thin air. Once we get hyper-inflation the house of cards will fall (or sooner). Not to mention in 20 years our average work week should be like 15 hours a week, not 40, and most jobs will be more economically done by robots and computers, not people, and we'll see some serious problems why some humans make salaries more than a 1000x times other humans' salaries.
