My advice for you is: Split your money after taking profit into 2 part: part 1 is for the initial capital that you should keep in fiat. Part 2 is the profit you get so far. You can reinvest by the part 2. In bad investment, you will not lose your capital, and only lose all your profits or have left money from your profit if the reinvestment get a loss of 50%, 80% or 90%.

It gives you a safe reinvestment. If you are right, and get luck, you can earn more profit. If not, you will still have your initial capital to use.
