Until now, i only baught crypto, but never selled. How do i get it back on my bankaccount? And what if nobody want to by my coin?
If no one wanted to by your coin - then you can't sell it. It's pretty simple. Case in point - would you buy Venezuelan dollar? If no one wants to buy at the listed price then the value drops to the point where people are willing to buy. If no one wants it then you're SOL.
The reverse holds true when everyone wants to own something. Take a look at BTC over the last few weeks.
