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.
The classic scenario has been case in your altcoin bags, so it is not surprising to see such feedback. The strong relationship with altcoin bags can lead to disaster because HODL-er will ignore the alternative options and only will focus on altcoins portfolio revenue. In order to avoid the same mistakes, investors have to make wise decision that can hurt at the decision time but better safe than sorry in long run. Generally, it is all about mindset.
