I was thinking of building my new PC in 2021, I built my pc without graphic card but while researching about other components like cpu, ram, storage, case, then i heard about GPU shortage cause of mining, and shortage because of people bought GPU 's very fast(in short time) after coming into stock.
I see, so you became interested in Bitcoin due to the GPU shortage and learned about mining and cryptocurrencies.
Unfortunately, you experienced a loss due to investing in altcoins during a bull run without much knowledge.
Researching and understanding the risks before investing in any asset, including cryptocurrencies, is essential.
