The reason for buying gold and Bitcoin is the belief that the hegemony of the US dollar will inevitably collapse one day. In 2016, the decision to buy gold was also based on the fact that gold's market value was the largest other than fiat currencies, while Bitcoin was at 300 at that time. Therefore, looking back, this judgment was not wrong. However, by 2017, I realized I was wrong because Bitcoin had already reached 3000. I bought a small amount of 0.1 as a hedge, but I blamed being too poor after just graduating. The real realization of a big mistake came after 2021.
