I looked at my phone that Sunday a couple weeks ago and was shocked to see BTC at 1900 USD and Ethereum in the 130's. I'd already bought some a bit higher and was thinking it would drop more as it had been dropping steadily over the course of a month or so.

Now I'm really kicking myself wishing I'd bought a whole coin on that Sunday evening using my bank account as the funds would have been available to move before the fork. I managed to buy as much as coinbase would let me buy on my credit card the day before the BCH payout and transferred it to another account pretty quickly but I sure wish I'd loaded the boat earlier.

Hindsight is 20/20. Ouch.
