You are right, many entrepreneurs take their business to new horizons. As a successful Bitcoin investor, I think their next step should be to take the next step according to their goals and preferences. Maybe diversify their investments, such as investing in real estate, startups and venture capital, or Web 3 projects.
Others may monetize their platform, community, or channel and expand their investment or skill set by sharing what they have learned by becoming an investor for a set fee.
I have also seen many people doing asset management work. If you are a knowledgeable Bitcoin investor, I think you can give tips to newbies and also maintain their assets by charging them a small fee or keeping a percentage of the profits.
