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 ?
Yes.
We can spot those that have gained already but knowing what are those altcoins that are going to gain that much, we don't know how to spot them.
If we do then all of us are already rich in this market because of those tremendous gains that they've made. We can find it out later when they're already pumping but, you'll be feeling regret to buy it at the top.
The truth is that a great deal of the time there is no way to predict which coin is going to skyrocket, many times a coin skyrockets because a pump and dump group took interest in the coin and then the members of that group bought the coin, and if you happen to buy the coin thinking it is going to have a lot of potential in the future you are going to be forced to keep a bunch of useless coins that never had any potential to grow at all, so while I can understand why people are tempted to invest in those coins, at least to me it is not a wise decision to do so.
