If you are a investor then your goal is to earn profit in a long period of time. I am a trader and perception of trader and investor are different. I only buy bitcoins if my technical analysis me a signal to buy. I keep making profit in a short period of time.
Investors and Traders are the same, I mean you can't be a trader if you will not be willing to invest some money on cryptocurrency, and not all of the investors needs a long period of time for them to earn profits. Based on OP's subject, my opinion would be, you cannot self-proclaimed that you are a Trader if you are just hodling your coins in your account in an exchange.
A real trader trades his coins whatever the market status is, thus he will gain profits everyday. Traders know how to take advantage of any situation that the market will give to them.
