I am not getting what you want to express exactly. A Bitcoin investor should be well-experienced and well Patience. Otherwise, they won't become a Bitcoin investor at all. I am talking about personal investment actually, not institutional investors. Because institutional investors are well-planned and won't regret their actions. Please write well instead of botted your thread. So we can realize what you want to explain.
As far as I know Bitcoin investors are people who spend money to acquire Bitcoin in aim to make profit from it in the future. Whether they are good investors or not depends on their action but I do not think you can only be label as Bitcoin investor if you are well-experienced and have good patience. From the context of the meaning of investor
in·ves·tor
noun
a person or organization that puts money into financial plans, property, etc. with the expectation of achieving a profit.
It does not say that they need to be well-experienced and have patience in order to be identified as one. Of course there are these labels to investors such as good investor, bad investors, newbie investor etc...
* they're risk managers
I don't think they are risk managers, because anyone who understands the high risk of investing in bitcoin would never invest on this coin. As we know cryptos are a high-risk investment and when we talk about risk it means the bigger risk is equal to biggest profit or bigger loss. so, those ones who know about risk and investment they would put bitcoin in the last spot of the investing options. And I know this because I had this conversation with some experimented Investors, and they just don't like cryptos because the risk doesn't worth it.
They can be, since they are able to minimize the risk involved in a certain investment. If someone understand the high risk and is able to mitigate this high risk can be said to be a great smart or wise investor. One of this kind investor is warren Buffet where he invested on the failing company and be able to rake huge profit from them.
