minus for 88% ? what was that mean . atleast they give roi , that still sounds good to me and means that they are not totally a scam . so its still okay to invest on them but idk if its really worth it or not .
all coins starts small but if they got lucky , thier value can pumped up so you can also earn huge too if you got lucky to invest on them . not bad to try putting small amount tho just to test them out and then add in the coins that you listed above as those coins are already established .
