You are doing quite well. I do not understand very much about finance, but have enough to still live. It seems you have several bases covered for any type of crash, but like most crashes, in time they all recover. The USA 1920's stock market crash, the first oil crisis of the 70's in the US, the housing bubble in the US, recovery was made, and no real big loss for those that did not panic sell. If you really are looking for advice, look at where during those crashes people put their money and put some there.

Like Booze, and stupid entertainment, not quality expensive entertainment, but cheap easy to access entertainment. Because people that lose a lot of money need something to do while they cry in their cheap beer. Also a little bit into gambling prospects, that is the other thing people do, they take big risk hoping for that elusive reward. But remember I retired, and do not have a lot of disposable income, so it is easy for me to tell people where to invest, because I won't be doing any investing, no money when working no money now. But life does go on, and I am almost up to 100 steem , so am having fun.
