Hello. Was participating in bounty campaign, have just checked my e-mail and found a letter, checked bountyportals spreadsheet and found that I didn't submit my ETH.

Is it still possible?..

Sorry for such a late answer...

Nowadays, bitcoin mining is not profitable. To take a benefit from bitcoin mining you should have $25000. So, better to buy btc and:
>hold
>hold and reinvest. There are some good projects where you can do that. If you are interested, I can suggest some.
>trade if you can. Buy low (bearish days), sell high (bullish days).

Or buy eth, dash, ltc or other alts.
