Heh. The complexity that's developed surrounding crypto, and the scams and governmental interference taking place because of it, is the greatest barrier towards its becoming useful enough to be an actually currency and that barrier may be insurmountable. To put it simply: Several companies started offering services that made it simpler to utilize crypto for practical purposes. Some of those companies were scams. Others were robbed. Others started restricting their customers to kowtow to governments. Some were just completely shut down by government. There are supposed to be some p2p distributed trading platforms that can take their place. Not sure I'd trust them, I haven't looked into them. I also suspect that at some point governments around the world are going to lock down the internet, *hard*. It will be made impossible for p2p networks to form. This reason given will be to "prevent espionage", or "block piracy", but a major reason will be to block crypto from working. (It will also break quite a bit of the internet's functionality and kill off some small companies, while the monopolies cement themselves further.)
