My preference is Ethereum over Bitcoin due to the high transfer fees involved with Bitcoin. I'm definitely open to many options as I'm still exploring this possibility. What apps or systems are highly recommended? Billing amounts will be either around $50 or between $500-$2k.
- First of all, almost anyone pays with crypto these days. What I did for my startup was to just list my wallet addresses for different cryptocurrencies and ask users to e-mail me after payment. It may sound stupid, but I tried CoinBase and it's API is super broken not to mention it exchanges so you don't have much control of your money. You can choose any wallet or even generate your own paper wallet. You can see how I did it here: https://iristech.co/buy-bitcoin/ It works and I have received several payments via Bitcoin but it's like 0.01% of all Iris payments so you don't need automation for this. Another thing is that crypto is volatile so you need to place some pricing which guarantees you will have some revenue. I prefer to add high pricing for crypto since most money coming from it are either from miners or people who want to avoid taxes. For the wallet I use Exodus. Seems nice and you can export your private keys.
- I think Stripe now supports bitcoin payments. Also https://gear.mycelium.com is pretty simple.
