Any coin will definitely had the chance on getting top spot ranking on a certain platform but if we do try to check out the liquidity and the volume then you would able to tell the difference
on what coin does have an organic increase compared to those who do just being pumped in a short time.About that polkadot project, from the name itself then i cant already trust it up.
I havent read up on whats the project is all about but talking about seriousness, the name implies the opposite.Its just my own view though but if you do chose up
to risk some money on it then its your choice.
