If I had 50k of extra capital right now, I wouldn't purchase additional mining hardware.  I would start trying to figure out where you think the bottom of btc is.  Learn to trade on some level.  No need to day trade.  Dollar cost average in what you want to hold for the next few years.  That's what I'm doing with my extra 15K.  I also wouldn't be hell bent on selling in one year.  Could be in for a disappointment, if this is loaned capital that you have to pay back in one year without interest.

i think NEX and nOS ICO's top in 2018. both from coming NEO blockchain. both project team and roadmap are massive.

I believe they both have integrity and they are good bounty sites.
The hype around bountyhunters site is because they are new and they are offering interesting offers and bonuses, there is a huge reward for referers and so everyone is interested to participate.

In bountyhive, they are established and regulated and they have a large stream of users, unfortunately they have launched bounties for failed projects lately, but still; they have better bounty programs and established referer rewards of 0.0075 eth.

Make your research, Do your choice and will.
