There are many coins that will flip 5-10x

my top pick is XCP, it will create smartcontracts via Bitcoin
other coins that I expect a lot of are SCORE, XtraBytes, Anoncoin (anonymous coins). I wouldn't invest in Monero (I liked it much, but transaction fees are too high), ZEC (they use zerocash which can be used in a bad way by developers, and if we are looking for cryptos they should not be altered/regulate by people)
Coins that DBT1033 mentioned Ardor, Syscoin, Florian I think are good picks (look what else he shills)
Some other people think highly of Solaris, I really don't know why but I invested a small amount in it.
A big sleeping giant could be RAIblocks #DYOR!
AdEx is a short term play that will do something nice.
WeTrust is a really nice concept, and could get rid of banks for good. It let stakeholders finance each other.
I liked Bitbay at first, but they want/are pegging the coin, which in my opinion is not good, so its a no go!
