If i will be given a chance to do a project with cryptocurrency then i will be making an all in one digital wallet for all crypto that includes bitcoin and all altcoins using same wallet address...
A wallet which does create the same
address for each crypto currency is not possible.
(Almost) each cryptocurrency does have its own address format.
What you might be refering to is a wallet which holds private keys for multiple cryptos derived from one seed. This is possible. And it does exist.
Exodus is such a wallet.
But note that quite a few people have connection issues when using exodus. It also just had a vulnerability discovered which allowed an attacker to dump the private keys out of the RAM once the wallet was opened. I am not sure about which versions are affected.
The ledger nano s does also support multiple cryptocurrencies. And in addition to that the private keys (and the seed generation) are secured by a secure element and a 2-FA through the buttons/screen.
Once they release their native application, you will be able to
monitor all your holdings in a dashboard.
It is only a good concept if possible to make a project like this because if this will be possible then it would be a revolutionary digital wallet for all cryptocurrency. As we all know that technology nowadays are really good and sometimes we could not go deeper on it and the only expert can tell us if this is possible. We are digital nowadays so there could be an application and i was thinking also of a conversion to all digital wallet who had been created will be connected and link together for a unified digital wallet. This will be awesome for sure.
