The French regulator AMF has published a warning against three new cryptocurrencies brokers.
Direct cryptocurrency trading on exchanges is not regulated, but trading with derivatives is. And it is precisely this rule that a lot of brokers break, they offer indirect trading without the necessary authorization.
It is the case of these three unregulated crypto brokers: Bitoraxe, Connect Coin and Solution Crypto. This is why the AMF has warned against them.
For your trading use regulated brokers.
