A lot of technologies have potential but die out from a whole bunch of executional problems, you were lucky that Bitcoin didn't, just like any investor in high-risk investments is. There are no fundamentals to analyse Bitcoin and there were even less back in the beginning, you made a bet and got lucky, that's about it.

I'm glad your bank account balance is healthy but again, you just made a bet, don't try to sell like there was a proper analysis that was in any way close to a scientific method to go through.

Cheers, enjoy your money, I don't care about how much you have, don't be smug about it.
