There's a specific answer to your question OP because each every one of those big investors has a different perspective way upon spending their money even those who start a business in crypto. But I have doubt that they will keep reinvesting or investing any new projects found that has the potential to gain profit. They are always thinking to gain profit since they are business-minded.
Business owners should have a plan in every cash flow, it is very essential for the movement of money in and out of your business. Not only for luxury stuff they want because the poor having cash flaws will result in a business failure. It's the same goes investing cryptos, you should always have game plan.
We all understand the financial conditions of many countries in the world, currently in a state that is not very good, the cash flow. The national business also does not run well because of the social distancing effect. We also know that exports are not very good as well as imports because the effects of the Covid protocol for each country are different so that the trade volume decreases, even in many countries there is de-globalization, aka the only domestic market leading to a recession.
With all the uncertainty, investors are waiting for 2020 to end before taking action, only a few dare to take risks in times of pandemic. In addition, investors are waiting for November 2020 when the American presidential election will be held, which is considered the height of the conflict between China and America. Few investors dare to make new investments, they only rotate the existing ones. Many investors are doing hibernate now by holding cash, if they choose to invest recently they choose low hanging fruit, which is a short-term business whose results are reasonable and there is freedom to quit, any time.
