This is in relation to Stormgain requiring you to use your bonus money or earning from mining to trade in leverage.
That requirement only works for earning withdrawn and in standy in your account. If you dont withdraw the $10 treshhold then it can continue to accumulate and is not required to be traded. The reason here is that the mining earnings is actually active, since it changes with the BTC / USDT price. Meaning if BTC goes up then your earning goes up, if it goes down then the reverse.
The advange is that you are sort of doing a HODL and wont have a liquidation call. The drawback is that you if have a good entry price during a retest or fake outs, you cant jump into a trade right away, if your miner is running. The work around you would say is withdraw and wait incase there is a good entry, this is the reason for the other article, you can only hold bonus earning for a certain time that it is not active. So you'll be forced to enter a trade that might not be on your side. I havent tried this but closing the browser restarts everything same as your inactive for a certain time, that way you can then withdraw and go into a good entry, thing is some good entries like flash sale where the drop gets bought off pretty fast and creates a big candle wick, it happens too fast before you can come it but this work around do work.
