Tangent Joint Creation: Nowadays, BTC is more affected by external factors such as ETFs and macroeconomics, and cannot blindly follow market sentiment When reviewing his investment experience in 2022, Tangent co-founder Jason Choi stated that he was too eager to invest $40000 in Bitcoin, and as a result, the price of Bitcoin later fell to about $15000. Although he timely withdrew to avoid greater losses, this experience made him realize the importance of market judgment. He mentioned that he has performed well in predicting the top of the market, but there are still shortcomings in judging the bottom and short selling strategies. Jason also pointed out that Bitcoin is now more influenced by external factors such as ETFs and macroeconomics, making market trends more complex than ever before. He reminded investors that 'greed when others are afraid' needs to be combined with the actual situation, and cannot blindly follow market sentiment. Rational judgment can bring better investment results.
