Fees are going to miners, not to the wallet devs.
I have some questions and please answer to them by number:
1- Which programming language is good for Blockchain programming? Is Rust-Lang good?
2- Can making a wallet be profitable?
Any idea welcome.
1. C++, Rust, Solidity (outside BTC)
2. In my opinion, the only way to make money with a wallet is to sell it, and I don't know who is going to agree to pay for a wallet (not open source) as we all have Electrum
Why would we pay for a risky option when we have a trustable free one ?
Wish you a nice day guys, and a happy new year 2023
