I bought altcoins compared to bitcoin because I saw the possibility to skyrocket greater than hold bitcoin, as we know that the price of bitcoin is already expensive while currently many altcoins are very cheap even if we invest only $ 10 then the opportunity to get big profits because new coins are usually will burn or pump big.
It's actually the same, bitcoin and altcoins have the same potential. On the other hand, some altcoins are following the trend of bitcoin. But it comes back to ourselves, where is the most comfortable place to invest, because both of them have promising ones. But when it comes to the long term, I think I would prefer bitcoin.
