Four kills: girlfriend not married, sold Bitcoin, house price dropped by half, still 25 years of mortgage.

Today I was chatting with a friend, and he told a sad story:
In 2020, to marry his then-girlfriend, he sold 90 BTC for 9,000 USD to buy a wedding house, but later he broke up with her due to some issues, and the house was a wasted purchase. Those 90 BTC are now worth over 10 million USD...…
Now this apartment in Beijing has dropped in value by half... so tragic...
