Another random thing I thought is that liquidity is a near non-existent for crypto with $14ish billion market cap, while forex is THE most liquid market on the world with $4 trillion volume/day.
Basically, forex deals with roughly 300x more money on a single (week)day than there are cryptocurrencies in existence; crypto is insignificant to the level of maximum global irrelevance.
Now, I'm not saying it can't prove to be a historic invention, eventually; we're just not there, and there are problems to be solved
*cough* scaling *cough*Okay, now bring on the hate!
