I have been doing my research on which good altcoin to hold, but i also need your opinion on which to hold.
Try ETH,XTP,NEO,BTC,Monero but that final decision only from you, They are a lot if respondent but are you sure that one of them, You will accept their advice? For me that is not good for investment. I advice if you want a good investment search by own time and good timing because me and the other can't help you out for this thing.
