What i think you should do is go to the coinmarketcap, take out some time to and research on the first 100 or first 50 or first 20 or first 10 it all depends on your capacity to carry out this research. This will be much better than waiting for OP to give you any recommendations as OP will only tell you to invest in what he knows and believe in and not what you believe in. This is 2019 mate and i also think you should be responsible for the decision you will take this year.
