If you had 1 BTC in Dec 2017. Sold it to stable coins and bought back in 1 year later, you would have over 6 BTC.

If you then were perceptive enough to sell those 6 BTC at $60K into stable coins, you would have $360K which you could currently buy around 12 BTC with. Bull markets are great fun, bear markets are where the money is made.
