$BTC

HODL is a term derived from a misspelling of "hold" in the context of buying and holding Bitcoin and other cryptocurrencies. It's also commonly come to stand for "hold on for dear life" among crypto investors.

The term originated from a 2013 online post to the Bitcointalk forum where the typo appeared. The price of Bitcoin in 2013 was volatile at the time, surging to over $950 at the beginning of December 2013, up from just over $130 in April of the same year.
