Some of these coins were pretty solid and im sure they will do just fine without Polo also. Polo is a huge player for alts but it is possible to manage without it also
Expecting the same thing already they are listed in other big exchange like Bittrex, many people are moving their coin to Bittrex.
But whether it is still profitable after delisting them from Polo? My question on this coin keeps on thinking twice because many devs did a lot of hard work for the past 2 years.
