You're very correct, it's very difficult to predict which coin will do a 100x return in the bull market but if you want to increase your chances of getting 100x the. You don't have to invest in old coins that already pumped last bull market. You have to invest in the newly launched project and those that have very huge hype surrounding them because hype means more investors.
The more investor a project has the higher the chances of it giving very huge return. The project you listed can all give you 5-10x and that's a good return to get in a bull market but to get the best results you have to use a very good capital starting from $500 or $1000l if you have more money to spare. Don't invest small because you'll only get a small return instead invest medium.
To get 100x I'll suggest some memecoins like Shiba Inu or Pepe because they have room for more growth and if they gain small percentage of what doge coin has gained it's going to be a very massive profits. Also you can invest in Artificial intelligence projects because that's what is trending now and during the bull market more money will be channelled towards AI projects.
