While in your server's terminal, install the wallets for the cryptocurrencies you intend to offer by running this command:
Use your up/down arrow keys and space bar to select your desired coins.
Do not select all cryptocurrencies at once. Rather, choose only those which you will initially offer. As each coin's wallet will begin syncing its blockchain, the more coins you initially select, the slower the syncing process will be.
Installation will take a couple minutes, though syncing the wallets' blockchains will upwards of a day. During this time you will be able to place funding deposits to your wallets (see subsequent steps), however, the machine will not be able to send transactions until the chains are synced.
To backup your Ethereum seed, after the install script completes, run:
Write the output down someplace safe in the order presented. This will back up your Ethereum seed.
However, your other wallets (Bitcoin, Zcash, etc.) must be backed up by hand: Wallet Backups
See more details in our article: Wallet Setup.
You may check the synchronization status of the coins you've installed: Checking Wallet Synchronization
