If you don't care about the money and feel that you can't use it in a short time, then take it to the capital market to make some venture capital for yourself. The FinancialConduct Authority in the UK still imposes strict restrictions and supervision on brokers or trading platforms, so the large institutions certified by FCA are still very clean and transparent. You can choose medium-rated corporate bonds, which are between B- and CCC. The expected annual income is generally between 5% and 8%, and the price fluctuates with the market, so there may be additional capital gains. If there is a book loss, you wait until the maturity date of the bond and the enterprise redeems it.
