If you are a person who has just bought Bitcoin and kept it in your own trusted wallet, I will not consider you a Bitcoin investor as long as you don't use Bitcoin or invest it in a certain company. Because if you are only limited to buying and keeping in your wallet, you are not much different from Holders and also from traders who also try to save for a while before they sell it back to the market. So there's no need to consider yourself an investor if your effort is to save before selling again.
