Crypto should go higher. So few people are smart enough to actually trade the market on fundementals, they're still reeling over what digital decentralized money means for the future... I expect more interest in crypto in 2018 and people investing into it more.
I now know several every-day people who now want to invest into crypto now that's gone up. Millionaires and billionaires are thinking likewise, the sector will see more money into it. And there is a decent reason for investing into it now, because some projects do have valid and compelling use cases, so they are actually worth something long-run. BTC should keep going higher in 2018, I believe. The rest of crypto will follow, the good, bad and ugly.
