Every coin has an official wallet with complete blockchain. It could take a lot of disc space on your computer.
You could also use a wallet address generated on a crypto exchange. 2Miners works fine with that.
Every coin has a help page "How to start" -> usually it has a link to an official wallet and/or crypto exchange that supports this coin.
