You do not need to take big risks with your Snowball to increase your income but it does help if you are ready to buy after a market downturn.

If you had just simply re-invested your dividends, you would have achieved the holy grail of investing in that you could take out your stake and MRCH would be producing income at a zero, zilch, nothing cost. If you had then re-invested the capital in a long term gilt you could achieve a blended yield of ten percent, with little or nor risk to your hard earned. You would then have 20k of capital invested producing around 1k of income to add to your Snowball.
