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.
Not all of them are shit imo, you can try look at Yobit exchange for full of shitcoins and if you are patient and have luck beside you then you can get something from there like in the past. Yet, the chances to get that is nearly to zero since it will die quicker.
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
Back then, even shit POW coins were considered tradable for short span amount of time. But in 2019, thing is really different now.
