Friend's running a patient advocacy service expanding to Europe. Clients asking to pay in $BTC & stablecoins.

Now he's asking me: what's the cleanest setup to accept crypto, hold the $BTC, and actually pay people out?

Real adoption happening in weird corners of the economy. Healthcare services taking crypto payments = underrated signal that normies are finally comfortable transacting on-chain.

Anyone running a similar setup for service businesses? What stack are you using - Bitpay, BTCPay Server, or just raw multisig wallets?
