I think all the small investors who have the habit of selling Bitcoin actually don't understand anything about investing. But I don't agree that big investors have a habit of selling Bitcoin, in fact they are called big investors because they buy Bitcoin regularly and own a lot of Bitcoin. That is, they are very experienced and patient, so they have been able to increase their Bitcoin holding, and even have a lot of patience to maintain their investment. So it would be wrong to say that big investors have the habit of selling Bitcoin.
Not only is prudent income necessary for small investors, it is much more important and necessary for all investors. In fact, in many cases, many use the words prudence and disposable income, so they should know properly.
Everybody needs to fix their profits eventually.
The thing is most smaller investors are not standing on the same stable ground as the bigger ones - they still need to think about their potential risks and much more, whereas guys in suits and a bit lower don't need to think about it.
Is not that small invests that have habit of selling their Bitcoin does not understand investment, most of them understand investment but the truth is that some of them don't have the financial capacity to solve some of their basic needs so when they have any financial pressure on them they tend to sell up their Bitcoin to enable them raise money to solve their financial problem. This is the reason why it's important for every Bitcoin Investors to have alternate source of income or a descrisionery income to enable them be able to solve their financial needs without affecting their Bitcoin investment for long holding.
