I think for now, all the Altcoins will likely survive 2021 unless something huge happens and set the space back like 2020 Covid 19 thing. In a bull market even shit of the shit coins pump like crazy, it is you that would be wise enough to know these projects can sustain their price and get out with profit
So many projects were pumped to the moon but these projects were going back to the bottom again. As far as i know the pump will be only for short term period for the crap coin.
The shitcoins will be dumped again while the good coins will remain stable and as far as i see if the market is very selective at this moment too.
People are also going to the coins that had very good fundamental. People will not blindly invest in the crap coins.
@jacafbiz, It was not the case of a bullish market cause only coins that had a huge enthusiasts fan base will benefit from the bullish market and the altcoins that are manipulated by the team involve just to lure investors.
Nevertheless, if you check the market cap you'll see that some altcoins didn't experience a surge in price till now.
@X-ray, You are absolutely right and this the reason why people need to be very careful when they choose their investment.
