I have used the safetyvalue trading platform and am in a wattsapp chat group with darkcheries. I have only ever deposited a few hundred pounds and have made a few small withdrawals without a problem. However I am suspicious of them now and no longer use the platform. They keep hyping ICOs and the opportunity to purchase prelaunch. However once launched I can not find them on any other coin exchanges. I belive a lot of the members of the watsapp group are fake and just add to the hype.
