you have no clue at all about comparing coins like zcoin with solaris
solaris have even not 1 known team member...
thats very very bad...
they can disappear and nobody ever would find them
or they had lot of times massive problems with their wallet..
1-2 weeks ago the blockchain was not working at all for some days (not possible to send any coins) etc
currently the Mac wallet is not working under new (apple high Sierra)
so use your brain a little bit more you chiller
yes there could be massive gains but also its extremely risky
