I personally would buy the property with some sideline cash left (as you mentioned 70/30% if that works for you). I guess in your case it would be an apartment. This is definitely much safer investment oppose to today’s very risky investment in crypto. Just hypothetically. Imagine if you bought crypto for all your sideline cash and in the next few months it drops by another 50%, which I wouldn’t be surprised at all. You would have sleepless nights and you would possibly panic sell (because most people do, doesn’t mean you would). Now imagine, if you bought an apartment and in a few months crypto jumps by 3,4...folds or more, you would still be able to rent your apartment and still be invested in crypto.
