The coins with potential to 100x you can find in the interval of 50-150 of coinmarketcap, but you should look for it carefully, because the are a lot pump coins which have no promising technology.
If you want to obtain 100 times your investment I think you need to go a lot lower, even those coins still have a very high market cap, you need to invest in projects that at most have 10 millions as their market cap, I know that can be very risky but if you really want to obtain such great profits you need to take huge risks.
I think lower marketcap will more help to obtain 100x from our capital. Higher profit you wish then it will be risk in the same direction. So for me get double is more than enough so i will be happy for that. I dont need much but put my capital very higher risk. Thats what i want
