The problem with Bitcoin is that it exists exclusively in digital form. Paper dollars can be withdrawn from an ATM and paid for goods and services in places where contactless payment is impossible, and there are still plenty of such places not only in El Salvador, but even in Europe. Another problem is that digital currency is not backed by anything and is only a speculative instrument. It can be worth one dollar a coin and you can't do anything with it.

Maybe Ethereum not yet adopted as payment method, but it has a huge impact on the pricing of gadgets.
Payback periods for most NVIDIA models have exceeded 20 months, and RTX 3000 cards without LHR under current conditions will return on investment for more than 22 months. The AMD Radeon RX 5000/6000 graphics cards perform slightly better, which will return on investment in 19 months. However, due to the plans of the Ethereum Foundation, miners will not have so much time to return their investments, because the transition to Ethereum 2.0 may happen in the next 4-6 months. All this makes the purchase of new farms an extremely hopeless activity and can positively affect the prices and availability of graphics adapters in 2022.
