Do i have to manually create a wallet for each of m?
It's not the best idea to store your coins in an exchange platform. Especially if you plan to store for a long time. You can never be sure that the exchange doesn't vanish tomorrow morning along with your coins. You could store them on a hardware wallet such as a TREZOR or Ledger, but still make a backup, or better a few ones on external disks.
