I know not your keys not your money, I will just be using it for micropayments, don't you start lecturing me on that
Don't use any web wallets, and especially not custodial wallets.
If you really want to use something for small amounts and micropayments, than consider using Lightning Network or Liquid Chain.
In Aqua wallet you have support for Liquid Assets L-BTC and L-USDT, but you can also accept Lightning payments and stablecoins from other chains (ethereum, tron, binance, polygon, solana).
Fees on Liquid Chain are minimal, for other networks there are additional fees.
