If you're wanting it for a Bitcoin node, id strongly encourage getting a refurbished computer like an off lease Dell and building with that. An i3 will be just as good if not better, and an i5 CPU will dominate compared to a pi. Plus you can have more memory, stable power, and faster disk I/O.

Pi is great when the cost is reasonable but no good reason to overpay for it's performance unless you absolutely need that platform and smaller form factor.
