No one knows if we do talk about on when it would gonna end and just like what other members been saying here that nothing to remains on the top.There would be always something better
on the current top coins in the market but it would still always vary with the demand because this is where things matter most.There are still some undervalued coins or projects out there
but didnt really get much attention and i dont know why and its up to you if you would risk on buying it.

Statistics? There's none and everything could happen in a  short span of time basing on communities interest.
