The best way to receive bitcoin is to be paid in BTC. Another easy way now is to buy BTC.
The right way to buy BTC is without KYC and Relai allows that. It means that the identification procedure is not used in the Relai app.
I think DCA (Dollar Cost Average) or an accumulation plan is a good way to buy BTC for a long-term strategy.
Relai offers this service, so is the right choice if you want to stack some Sats!
You send a SEPA transfer and you receive BTC into a non-custodial wallet (not your keys, not your bitcoin!).
Relai is a Bitcoin-only company, the app is nice and so easy to use, so as a bitcoiner, I recommend Relai.
