And miners also don't charge any fees because you pay those to compete with the others that want your block space, let's not get into this debate
What debate?
I need a web wallet that can deal with multiple coins, not just Bitcoin, so if somebody wants me to send him $10 worth of USDC on Solana I don't need a solana wallet then another one to receive 100 satoshi and another one to send 50 monero.
I am using Unstoppable wallet for more coins because it is open source. Good online open source wallet is hard to find. There was a time I am using Metamask wallet.
Most online wallet withost coins ar close source not I can it recommend close source walleto.
If you can get a hardware wallet like Trevor, it is better. It is also open source.
