Mine is pretty epic. Way back around 2011, I discovered bitcoin. It was $50 a coin. I thought about buying a dozen or so, but I thought, "Nah, this is a fluke, its a scam, the price will probably go way down." 2 weeks later, it hit $1200. Ugh. *Palm to forehead!*
Now, I look back, and if I bought those dozen bitcoins for $600, my BTC would be worth around $36k.
Point? Sometimes you gotta take risks.
What was your worst cryptocurrency blunder?

In 2011 Bitcoin never got much above $20. It went sub $5 again in 2012. The last time the price was $50 would have been March 2013 and it took about 7 months until the price of Bitcoin hit $1200 in November 2013. So, you had 2 years to act at sub $50 and failed to do so! Don't sugar coat your blunder
Ah well, if you had acted, what would you have done with $36k?
