Soilcoin. It's a coin with an extremely low marketcap, but insanely huge capabilities. Think about this:
It's current marketcap is 333k
If it grows to a reasonable crypto with a marketcap of 1b, which is very well possible for such a competetive coin, you would've multiplied your investment by 3000 times... It's risky, but could pay off VERY well.
They're available at Cryptopia, which is one of the best exchanges around. The only disadvantage is its low volume, but when Soilcoin becomes more known, that volume will increase and it will grow a lot in value!
I recommend you not to put thousands of dollars into it, but just a small amount, for if it succeeds, which could make you a ton of money.
