Part of the point of this is it's a fairly lazy portfolio, not checking the charts every other day to see if it's a good time to get in/out. Just check the trend every week or two and adjust accordingly.
Assuming it continues to work in the future (you know, "past performance is not an indication of future performance") it's a good strategy to fairly safely (or at least, lower risk than crypto) increase your investment 'foundation' funds.
