There are so many crypto wallet apps out there including Trust Wallet. Some wallet have a pro version to buy, but most of it are free to download and use and didn’t charge you anything except the network fee for your transactions.
Question: Since the network fee is not from the wallet itself, how do they makes money?
Okay, maybe for some new blockchains. I don’t think that hundreds or maybe thousands of erc-20 shit-tokens ever pay anything since lot of them are made for fun.
