From our experience in the agora shop, we can say all the customers pay in Bitcoin, how? We simply do NOT accept any other payment method.

Payments split between onchain and lightning change, it mostly depends on volume, higher amounts tent to be paid onchain, especially when mempool fees are low.

Technical issues help make improvements, adapt to market and software upgrades. Would be not fun and there would be no learning without it. I agree, for many it's easier to have a third party taking care of all the issues and focus on products, services, and sales.

I'm curious to hear what others experience too.
