Bitcoin Lightning Network is perfect for small payments, now you can accumulate a few satoshis for free from faucets and CPU mining. You can exchange those altcoins into Bitcoin using the services of cobo.

To receive micro and small payments lighting network is great, I collect about 1500 sat every so often from coinpot. You don't need to hold altcoins you can hold the real bitcoin.

You need to have room to receive in your channel I plan to use my channel for these sort of things and once I fill my channel again sent it back to onchain.

Today 1500 is just $0.10 in a few years that can be a month worth of work.
