I don't think there is any other crypto currency which is undervalued other than Bitcoin. Yes! All other cryptos look very bad infront of Bitcoin. Looks like most of the cryptos will die one day or the other. It is even riskier to invest on these cryptos for long term.
Same thing when bitcoin start to pumped and alts followed then another side of stories will show up. Crypto will be there to stay maybe there's alts that will die in the long run, those who don't have any usages but for those that have good use they are just waiting for the healthy market and sooner it will
rise back and give good value for investors investment.
