Cardano seems promising.
Cardano is number 8 coin, worth 5.4 billion dollar marketcap. How could you think that for 100x? You can't pick top coins to make 100x. You need to select from lower marketcap numbers. Let's aim 1 billion marketcap after 100x. You need to check coins that have less than 10 million dollar marketcap and promise something good to be 1 billion dollar coin. It must be unique project.
Look at the top 10 coin prices this time last year and compare to now, most of them are up x50 to x100
