Why is Turkish coffee also called good luck coffee?

Turkish coffee is often used for divination.

Ordinary coffee can't be used for divination, because coffee divination mainly uses the residue, shape or pattern left after drinking coffee to predict good or bad luck, so it can only be used for divination with Turkish coffee.

The principle of coffee divination is mainly to predict things by observing the pattern formed by the residue after drinking coffee, similar to Rosa ink test in psychology. This kind of divination can be done by yourself, or you can find a coffee soothsayer who specializes in divination for yourself. In Greece or Turkey, you can often see some coffee fortune tellers who specialize in answering questions in coffee shops.
