When someone has a particular wallet which he spends Bitcoins from can he be considered a Bitcoin investor?
Or does the term investor refer only to those who hodl Bitcoin?
The term bitcoin investment basically refers to people who buy and hold bitcoins. You cannot become an investor just by using bitcoins, becoming an investor requires high skill and experience. For example, if a person trades Bitcoin daily and holds it for a long time or holds it for a short period of time, they can be called an investor. And if you invest your money in bitcoins, then you are definitely an investor too.
