I believe participating in airdrops is one the basic way of doing this. Airdrops can be defined as the process whereby a cryptocurrency enterprise distributes cryptocurrency tokens to the wallets of some users free of charge. Airdrops are usually carried out by blockchain-based startups to bootstrap their cryptocurrency projects.

Although most of these airdrops take time before they are launched out, but not withstanding, you have nothing to lose and everything to gain when you participate in airdrops. Heaven knows how many airdrops I have filled and how many I will fill in the future but all I know is that if all decides to launch their coins then I don't know how much I will have.
