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 would classify 99% of the altcoins as shitcoins, because they are either copycats of the already existing coins, or they don't have anything unique about them. Back in 2017, a lot of the inexperienced users rushed to invest in cryptocurrency and some of them made investments in shitcoins without proper research (and in the end incurred heavy losses). That scenario is not going to repeat, so please invest smartly in good coins.
