It is risky if you buy it with your speculation that it will rise more after a few weeks or several months. If you do it without awareness that $100,000 is likely a new all time high of 2024 and 2025 bull run, you will sell your bitcoin when price drops back to like $60,000 or $40,000.

Many people thought the same when Bitcoin hit $2,000 or $20,000 or $60,000 and they want to be outsmart the market. If Bitcoin hits $100,000 or $200,000 many of them will feel regret about their past decisions.

Like a stock of Berkshire Hathaway Inc Class A, it is traded above $500,000 and is it expensive? Is it stupid to buy that stock when it was $100,000 in 2006 ?
