Isn’t keeping the right question(s) in one’s head crucial ?
Can we spot the coins that did this on coinmarketcap ?
Can we then trace back and see what happened and spot some kind of pattern ?
probably it's possible by back testing.. But such leverage seems impossible wherein looks for a coin that making hype only and then rug pull.. Lol by the way mate you should try making research first which coins read made hypes in the previous or past bull run maybe there are some site that provide list of them. If you find some then back test if you want to see some good patterns..
