I really don't see any real advantage of using your wallet compared to centralized exchange, and we can argue that it's much bigger chance of you getting hacked and customers losing money.
Depositing to some centralized service like blindmixer just to save on fees is so stupid and could cost you much more down the line.
blindmixer brings lightning to the average Joe. No longer will you be required to set up your own node, or use a separate wallet for your lightning transactions. blindmixer allows you to pay and generate invoices from the comfort of the same wallet.
This is nothing special to blindmixer, many lightning wallets are custodial and they don't require from users to set up own nodes, but that is much less secure and users have no control over coins.
Help! I have to trust blindmixer and/ or the custodian operator blindly?
Unfortunately, yes...
https://blindmixer.com/faqThat means that custodian can change dates, make wipes whenever he wants, so it's more like you are keeping coins with some gambling gangster and you need to trust him.
You can even receive your own coins back, that is unacceptable if we are taking about mixer, so this word should be removed from your service, it's just centralized gambling wallet.
