even though they might be rising, but I don't think they are good investments anyway, moreover the moment you see they rise that much you're already late, better invest in something better like BTC, even if you see right now BTC is gaining value quite good enough compared the rest, investing in those shitcoins you just mentioned just gonna be waste of money. Even though i'm sure that pump was made not by whales but by some desperate holders that still think those coins gonna regain its former glory.
I think only emerging coins and relatively well-known altcoins are worthy of my investment. Because the new coin doubles in price easily. I will not pay attention to some dead altcoins, even if its price rises, I think the risk is relatively large.
