HODL
“Hodl” is originally a spelling mistake made by a user on BitcoinTalk, where the user actually meant to say they are “holding” Bitcoin. The misspelling evolved into a slang in the cryptocurrency community, which now means investors hold on to their cryptocurrency regardless of the price, and eventually became an acronym for “hold on for dear life.”

Greater fool theory
Burton Malkiel first discussed the greater fool theory, which says that as an investor, you can buy stocks that are clearly overvalued and still make money. According to him, people are generally drawn to assets whose prices are rising because of biases in human behavior. This problem is exacerbated by the herd mentality, in which stories of immediate success by others tend to spur others to follow suit. A "greater fool" is always available to purchase an asset, the theory suggests.
