This is my top 3 favorite picks for 2018 and this is not what i think is most profitable this year its just what coins i believe will succeed and have an actual decent use case and also with quite low market cap.
#1 DeepBrain Chain. Deepbrain Chain is much like golem except it is focusing on AI instead. With a decent team and AI in heavy focus right now i think DeepBrain Chain will succeed.
#2 Power ledger. Renewable energy is something i really believe in and also with the Asset germination event coming up in 2018 i think it will be a very good currency to be invested in.
#3 Vertcoin. This one does not really have a use case like the rest its more like litecoin except it has way lower marketcap and also is ASIC resistent which means in my opinion it could go really high. Also something to note is that it is getting a VTC/USD exchange called vertbase soon and i really do believe this coin could go high.
This is not financial advice and i do not think these are the coins that are gonna 100x or 1000x but i do think they are some what "safe bets" if you could call a cryptocurrency that. If you are invested in any of these cryptos or in any other quite low marketcap cryptos comment it down below! Thanks.
