About altcoin to buy, I think BCNEX is one good altcoin to buy, they are a token owned by a Vietnamese Exchange and have all its legalites to operate.
I've seen some signatures of this project, I'll definitely gonna look on this now.
Exchange are popping everywhere but I like those exchanges that are regulated and compliant already this year, as eventually all exchanges will be regulated in the long run.
I'm checking it now and it says " they already raised $28 million" - they have a good funding.
