Do you have to pay or purchase to sign up?Storm gain is an app where you trade futures on crypto currency. Basically Forex for crypto. If you sign up with my link, you get a free 3 USDT sign up bonus. (Tether, backed by USD so it's always more or less equal to $1.) Storm gain also has a free bitcoin miner on their app where it will mine some bitcoin that you can use for trading.

You can trade the Bitcoin mined and withdraw the profits from trading mined funds, it says you can't withdraw mined coins, but I haven't checked if you can convert from BTC that you mined to something like LTC and withdraw that to another wallet/exchangeCan you simply mine bitcoin on this app for free and then withdraw to a wallet?
