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
I have heard of people having funds stolen using that site. If you have a weak passphrase or a trojan in your computer, you can be vulnerable no matter what website you use. I recommend using 2FA when possible and regularly changing passwords, and even better is using a hardware wallet - they are cheap nowadays.
