Yes i agree with the fact. Heisenberg would have that all of the coins that you just stated in a thread with the mention of crap coins now have the potential to become or remain crap. The crypto markets are dominated by the control of the value and price through sheer rumors and manipulation. Need a lot of study and experience to find a good coin with long term benefit.
This about sums up it for me. You could add like 10-15 more coins and basically make it an ETF and hold everything long term (if you think overall cryptos will crush) or alternatively you should study figure out which coins are best and go from there. Most of the coins are legitimate and will do well, but the time frame for all of them is different so you may want to look up on them and see what they are up to. Hope that helps
