There is still a way to get steem from CPU mining if you use nicehash, as described here, by @cryptos.
Basically, your PC mines from a selection of other cryptocurrencies, then nicehash pays you in bitcoin, which is used to purchase steem through @blocktrades (blocktrades.us). The only drawback is that nicehash and blocktrades probably both charge fees, but for me, the ease and convenience outweigh the fees.
I've also seen some posts about mining steem through genesis cloud mining, but I haven't done it, so I'm not sure how that works.
yeah i already trading using BTC and other alts i know i can buy, also i used nicehash before, its easy but the problem is you have to keep mining for like a week non stop to get paid for external BTC wallet.
So what am going to do i will buy using my extra btc from alts, Thanks for the info :)
