What do you mean with registration process process?
Do you mean without having to send your Bitcoins to a new address? Or is is that you don't want to create a new wallet?
If you are looking for wallets that support multiple cryptocurrencies, use Exodus or Eden (depending on which altcoins you are looking for); I recommend you to just create a new wallet and just send everything you have from your old wallet to your new one. P.s: Please don't forget to save your backup phrase to avoid losing your funds.
- Exodus[1] currently supports:
Aragon, Augur, BAT, Bitcoin, Bitcoin Cash, Civic, Dash, Decred, EOS, Ethereum, ETH Classic, Gnosis, Golem, Litecoin, OmiseGo, Qtum (ERC20) and SALT;
- Eden[2] (which is an more advanced version of Exodus) supports everything that Exodus has, but also:
