An investment in cryptocurrency has very high market risks. How to feel safe being your user?
No one can guarantee absolute security, if we are already talking about these 100%, then run out of there, this does not happen!
It is very difficult to give such guarantees and it is not fair to the user, if you start with such deception, then I doubt that the exchange will stand afloat.
It is necessary to promptly eliminate problems, if they arise.
