I built a high frequency trading system on early mount gox and had a ton of bitcoins as a toy project. I abandoned it because everyone kept telling me I was wasting my time.
I would be a billionare today— How do I deal with it? Just move on. Ultimately it is our own fault for not doing what our gut was telling us. So just move on and do something else.
I heard about BTC very early and I considered buying some. If I had invested even 1/10th of the amount that I was putting into individual stocks at the time, I might be extraordinarily wealthy today.
I say "might" because I recognize that I would have undoubtedly sold some along the way. Maybe when it hit $500, $1,000, or $10,000. I would have been a fool not to have sold any along the way. So it's easy to look back and think of what I would have had. But I'm overestimating the gains I would have actually realized.
There's also opportunity cost. If I had put a few thousand into BTC that would have been less to invest in individual stocks. The stocks I ended up picking did very well. Not as well as BTC! But close inspection shows the difference is not as great as it seems in my BTC-dreaming mind.
In your case the opportunity cost might have been your relationships. Think about how busy you would have been running a company that is so successful. It would lead to great wealth. But it would also cause stress in relationships. Maybe you have better relationships because you didn't hit it big. And maybe your relationships are more genuine because your friends are not benefitting from your largesse.
