Will I face taxes if I’m paid with bitcoin on cashapp?

So I currently have someone paying me $450 a week via cashapp. Not a job just a relative paying me weekly. Ive been interested in the idea of having them pay me in bitcoin via cashapp. (They are very stupid and can barely work cashapp so any sort of crypto site or whatever will be too hard for them) My question is, if they pay me 450 a week in bitcoin, and I hold the bitcoin in my cashapp account long term, will that bitcoin be subject to taxes if I sell it years from now? I know cashapp will charge their own fee just for the purchase of bitcoin, 1.75% iirc. Would it be worth it? Or would I be better off taking the cash and putting it into a bitcoin ETF? Strictly from a monetary point of view.

If there's a better crypto site that isn't technically difficult to navigate for someone with a bird brain, id be open to that too.
