I only like Bitcoin and Ethereum to invest. I already have invested about $4000 dollars ethereum and $ 10000 dollars Bitcoin at lower price rate and hold them for future .
Same here, but I focus on ETH. I invested when it was at about 80, it already pays back.
I expect the trend to continue its upward movement in 2019. As for ICOs, I doubt many of them will survive or bring any useful product to the market at all - their time has gone, I expect something else will appear in 2019 to begin to replace them.
