Bitcoin is volatile. From everything I read though, it is only going "up".

I first put some money in on January 29th of this year. It was at $33,817.51 at the time of my first investment.
I have made several since them. My last purchase was at $64,073.99. So in less than 3 months, it almost doubled. By April 29th, it wouldn't surprise me if it has doubled since the date of my initial purchase.

I would not get to caught up in the big swings. With the U.S. debt where it is, and with no end in sight to the spending spree, I don't feel you have made a bad decision in buying some. Your worst decision(mine too) may be not buying more.

And if it is good enough for Elon's company, it's good enough for me. It's actually not just Tesla, there are other companies who are jumping on board. I believe the city of Miami is even involved with it in some form.
