Quite interesting. Nevertheless, 2 questions come to my mind. Don't you think that low rates are there so power people can get cheap assets? The economy behaves in cicles, in some time it will rise up, this is the time to buy, you may don't have the money to buy but you can get it in low rates if you know how to. The one knowing that can take advantage...
On the other hand, how can you access cryptocurrencies? You would need some kind of cryptocurrency loan (binance have something like that). But producing cryptocurrency can not be from nothing. Nothing is free. So it should cost something, how to pay that cost?

Really nice article,
Best regards,
