Tbh, you really scared me with your title. I am of the opinion that anyone that is not buying the top 10 coins is at a very big risk to lose his money. Here I am seeing someone encouraging people not to buy from the top 50 coins.
I mean, do you know the level of risk that is involved?

Buying out of the top 50 coins literally means buying the shittest coins ever. I would never try this unless I am already a billionaire looking for where to waste money, I can then head to your advice and buy the coin you are shilling.
