And that is exchanges who are keeping coins/tokens hostile for a long period of time. When I deposit or withdrawal from an exchange often times it just keeps it in pending status. Now I'm waiting for an idex deposit, 4 hours passed. My worst case was a withdrawal at cryptopia which took 30 days.
Crypto is not ready to be adopted by the masses. Lots of suicides would be the result...
I think your case is not the most frustrating about cryptocurrency. The most frustrating moment in crypto for me is, when the crypto price falling too much in the market, causing you doubt to buying coins again or no. Look at the market price now, it getting worse in recent days.
The cryptocurrency value is too volatile, that is the most frustrating thing at least for me.
