Many community members have been claiming lately that altcoins are going to die or at least that 90% of altcoins are doomed. I tend to agree with them that there are many coins and tokens that are pointless and won't survive. Another cathegory are alts with solid foundations but won't manage to fight with their competitors as naturally there are numerous projects with same visions. But if you trust the project you invested in, there is no reason to change your mind just because someone says many altcoins won't succeed. Do your research and trust only your own judgement, because many ALTCOINS ARE HERE TO STAY!
I agree that many altcoins are here to stay but we need to weed out what coins are here to stay in my opinion I still trust those coins that are in the top 20 because of they already are a stable coins, they have nothing to prove, but there are coins on the ICO that also deserves our attention.
