Read the following paragraph. You will be asked to explain the observations made within using your knowledge of economics.

Graphics processing units (GPUs, often referred to as graphics cards) are used for image processing in computers and are responsible for the output of graphics to the monitor or screen. It was discovered that these highly specialized electronics were useful for the computations of parallel tasks unrelated to graphics processing. In particular, these were highly useful for the mining of cryptocurrencies. Crypto miners began to purchase large quantities of high-end GPUs for this purpose, with more and more individuals engaging in this activity as the price of cryptocurrencies rose in 2020 and 2021, with Bitcoin rising from a price below $10,000 per coin to above $60,000. During this time, the price of GPUs also rose, commonly being set well above the MSRP for their models. Additionally, fewer gaming computers were purchased during these years. Following the crash in cryptocurrency prices in 2022, with Bitcoin's price falling as low as $16,000, many crypt miners sold their used GPUs on the secondary market. Subsequently the price of new PUs fell drastically, with typical retail prices below MSRP. The availability of gaming computers has also increased since this crash.
