how to phrase 'managing personal portfolio' on my IBD CV

I spent a few years in IBD and then quit over a year ago as I was burnt out, wanted a break and a chance to focus on managing my own personal stock and crypto portfolio ($5m).

I ended up taking over a year off and I really did nothing during this time.. I completely lost my IBD skill set (forgotten everything) and work ethic.. all I did was chilled at home, watching Netflix and managing my own portfolio and now I'm quite bored.

I honestly thought I was retired for life and gonna live like a king but it was really the opposite.. I was bored, losing money and stressed. The past year made me realise how difficult it really is to retire, even with this large sum of money, the world today is just too expensive to live without a constant stream of income, even tho I was living a very cheap and non-glamorous life.. I was still eating into it at an unsustainable amount e.g. I started the year around $8m and given markets are tanking I lost $3m and now my portfolio is around $5m which is scary how fast it can drop, so I've now moved my portfolio into very low risk strategies. Plus, my spending on property rent, food and general spending is all going up due to inflation.. so I realised I probably should get back into employment so I can start earning again. 

However I'm unsure how I can put this on my CV to explain my time off. My personal portfolio is quite large and probably more than some hedge fund PMs manage.. however if I write managing my personal portfolio on my CV it just sounds cringe and without anyone knowing it's over $5m they will just think it's some $20k ISA account and laugh when they see it.. but then I also can't risk saying how much it is because it may cause jealousy or make it look like I'm bragging and employers may think "fuck this guy" and constantly laugh or reject me. E.g. what manager would want to interview or hire a junior, knowing the junior is (most likely) richer than him. They will always think about it in the back of their head.

Any advice what to do and how to phrase this on my CV and get back into work? thanks.
