As a long time crypto enthusiast, I’d advise people not to buy coins that already made a big jump. There’s more chance of you losing money as after a big jump whales/investors start taking profits and the coin goes down/sidewise for some time.

Patience is the key, if you missed the train then for the time being wait for the price to drop.

The biggest advice is to do your own research, sometimes a coin jumps big time then it drops and keeps dropping to oblivion.

Also be wary of crypto influencers. Some of them buy coins before they are available to people. Then they hype up their fanbase and influence them to ape into their preferred coin, which drives the price up and the influencer selling their coins making 10-20x profit.

SO BE VERY CAREFUL ABOUT THE INFLUENCERS. I the last 8 years I’ve seen this happening quite often. Won’t say all of them are bad, listen to their opinions and their views about fundamentals but don’t buy if they tell you to buy because as soon as they tell their fanbase to buy the value of the coin will jump. Wait for the price to come down before you buy.
