I think there is a very big risk to lost money on illegal market. That is why crytpocurrency have so bad reputation.
Once again: we ignore the risk of losing money when exchanging.
In my experience, this risk is
very big risk
, no - small. Of course, if you act carefully.
People are frivolous and inattentive at first, and then blame the circumstances that they themselves have created.
Cryptocurrency market is not secure. Hackers continuer to hack the exchanges. Today exchange Bitpoint was hacked and people lost $32 mln.
