In January 2021, I bought my first $BTC recently, with a cost of about 88,699. Below is a pyramid buy order. -> As macroeconomic conditions become more turbulent, holding fiat currency and US Treasuries is becoming less and less profitable. Other top assets (including US stocks, A-shares, gold, and silver) have already experienced a wild surge, and it should be about $BTC now. -> Global tax collection and compliance tightening are also major trends. The US policy on sovereign funds allocating to US Treasuries and US stocks has also started to fluctuate. Therefore, $BTC , as a non-sovereign asset, still has strong appeal for large funds in terms of privacy, security, and water avoidance. -> $BTC has a certain logical connection with mining prices, meaning it is an asset supported by electricity/energy costs. AI has propelled electricity/energy-related assets, so could it also be our turn for a surge? -> The only concern is quantum technology, which has advanced too quickly recently. I have also bought quite a few quantum-related stocks in A-shares and US stocks. But if something really goes wrong, traditional financial cryptography will definitely fail before cryptocurrencies. Since banks will fail before me, there's no need to panic excessively.
