Which BITCOIN mining company have you invested in???

Just curious..

lost some money in there.
got some good companies also. 2 companies gainbitcoin & ethtrade (btc & etherium respectively) i invested in are paying and still paying after my break even point there since almost 6 months ago.
does any of you guys used these platforms or any other..
