Security, High Risk, Scammers, Hackers etc. can be the problems. What do you think?
You mentioned it right these are the usual problems of investors generally.
Well as a trader my concern is not only that, I also have problem when it comes to deciding. Decision on what coins to buy and how much amount to risk because of uncertainty.
In the end it depends how you deal with your trades and the problems you may encounter.
As long as i involved in cryptocurrency since 2017, i've never experienced one of those things. It depends on how safe we're doing activity at cryptocurrency. Maybe hacks and scams are everywhere but if we are secure on browsing crypto websites and keep safe doing crypto transactions those things won't happen i'm sure
