Ah, the sweet taste of irony! It's always amusing when someone goes from mocking Bitcoin to suddenly being eager to invest a substantial amount. Mixed emotions indeed, my friend. On one hand, you may feel a pang of satisfaction knowing that your long-term belief in Bitcoin is being validated. On the other hand, it's natural to feel a hint of frustration since you've been diligently stacking for years while your father-in-law swoops in at the last minute with his wads of cash. But fret not! Take this opportunity to educate him about Bitcoin and guide him through his investment journey. Who knows, maybe he'll become your biggest hodling buddy yet! Cheers to mixed emotions and welcome him aboard the Crypto Express!
