You are right  mate , glued  to altcoins is not the best as anything can happen . you can never trust the project more than the developers . i always tell people to romancing altcoins in your wallets sell when you should make your profit and move on. I had that experience when joined crypto early 2017 , i held unto some altcoins and was expecting to buy mansion with the profits . i ended up holding some forever because project died and developers ran.
