I'm aware that I could simply offer Bitcoin as a payment alternative... Of course, I would do that as well, but I'm looking for something with a bit more connection to Bitcoin.
When you say a bit more connection to Bitcoin, I would remind you to first and foremost view Bitcoin for a currency as that is indeed what it is. Any attributes or things you could do with your fiat, it’s applicable to Bitcoin as well, just ensure you have a retrieval strategy as, it isn’t like fiat and leaves no room for mistakes.
That means, you either get to buy and hodl, trade it, loan it, accept it for a means of payment and a couple other uses out there. It doesn’t get much better than that. You should ensure you do proper research of your own while using the information you gather from others for guides.
