In my opinion you must not underestimate the strength of the cryptos, because popularity of it is rising gradually, every day
We dont talk about underestimate mate but we ask here why?
If you said that the popularity is rising then it might be the answer why.
But that is not the only reason since popularity is the general reason and the only crypto will be pumped is the coin that have good promissing and good idea. Good development can be the reason of pump too.
