can they be hacked, and the funds stolen, do they have a special wallet where they keep all the btc ? how do they work exactly?
can they suddenly decide to hold your btc, or restrict you or prevent you from sending or receiving bitcoin ? if you don't provide id or for whatever reason ?
do you own your btc (menmonic) with them or is it in their control?
thanks
Now a day anything can be hacked it's a like a play game for a hacker
Online app things sites it's not difficult to hack
That's why they are called a hacker
Because they know everything
