When you overpay for something because it seems like it seems like it is going to be awesome but then it just turns out to be a worthless overvalued clunker. Kind of like Carl Crawford, the Red Sox high priced free agent outfielder.
I bought this watch on the Internet for $500 because it looked like a Rolex but in the end it's just Carl Crawful.
Craful means to be careful, to be alert and attentive. It means to watch yourself, buddy. When someone gets too excited to need to tell them to be craful.
A term for a person who is very careful in their decision to invest in cryptocurrencies, acknowledging the fact that investments are a very volatile gamble due to constant "pumping and dumping" and much more. Currently, while terms such as hodl are very popular amongst crypto investors, craeful investors are generally more knowledgeable on the security of capital and responsibility. The term was coined by John Oliver in an effort to inform people on the dangers of such an investment.
