10altcoins.com is a big scam! They tell you to depost 0,03 BTC (300€) to be verified.
Dont do it!
After that you still cant withdrawal and they tell you put 0,0315 btc more in and THEN you will be able to withdrawal.
So I lost my 0,03 btc I don't want to send them again my money. Scammer... $#*!ing scammer really. Where is cybersecurity?! Come take them down from Internet.
