Nvidia Profits: Cyrptocurency boom fueling price increases and growth

Cyrptocurrency is presenting many challenges to governments and other organizations. However, the biggest challenge and opportunity is for graphics cards, also known as gpu, sales. These gpu's power what is known as the blockchain and allow transaction to happen. Without these graphics cards, there is no cyrptocurrency, besides bitcoin basically. This fuel for people to make money mining, is driving up the price of graphics cards, often to double the MSRP. All graphics cards are in short supply. Is this intentional by the gpu makers so prices go up and they make more money? It would seem to be the case as NVIDIA just released record profits, and can only speculate it will continue. What happens when crypto bubble bursts? will it destroy their business? only time will tell. what are your thoughts?
