2017 is in the past now and dont expect shitcoins will bring you profit like it did in the past,you have to review your portfolio and make sure that every tokens and coins you holding are worth been hodl.
Try not to pick coins because they are mineable or they have actualized POS,coins without genuine use case will bite the dust additional times and lose esteem,this is 2019 and crypto world is reshaping, make the smart move
I have realized it now that it's not always a good idea to keep a dozens of altcoins in your portfolion. Not at least for me. A 3 to 5 would be the ideal number of altcoin to hold as you can easily follow them and trade in and out whenever you find the signals. The current strategy has increased my overall profit and it's easier to keep a track of my investment.
