The best way to do this is the look for altcoins that are releasing great futures but that are currently low in prices. A few google searches will help. For example i found this hidden gem called bird token. Its from the birdchain company.
Birdchain is looking to launch a DeFi swap and NFT platform. When they do, early holders of bird token will rip the rewards because they got on early.
If you you're looking to x100 your money, i recommend you swap birdchain now,
