Yes and yes.
I made the exact opposite mistake in 2017. Can you believe I sold bitcoin to by my wife a Honda minivan?
That minivan cost me about $407,076.33. Roughly. More or less. Not that I’m counting or anything.
If I would have borrowed the dollars and bought the minivan, I would have been up $350,000 or more.
If I would have borrowed money, fixed the old minivan and bought bitcoin with the rest, I’d be up $700,000 or so.
I have a decent income, so all of this would have been possible for me. But I was too proud to borrow dollars and too risk averse / too ignorant to buy bitcoin on leverage. Leverage requires restraint and properly sizing the amount of leverage one uses it’s not obvious. I still can’t borrow to buy bitcoin, even though intellectually I know I could/should do so modestly.
But what I have learned: once you start selling bitcoin, your stack will never be that size again. Or probably not. I’ve bought back the amount I’ve spent on the minivan, but at a dear price.
Not my first mistake selling bitcoin, but the earlier ones are still too painful to talk about.
