When money is cheap everyone tries to borrow as much as they can and invest it in assets that they think will appreciate faster than inflation. It's worth remembering though that pretty much every crisis in history has appeared out of nowhere and taken pretty much everyone by surprise. Just look at Covid - Bitcoin fell as much as the stock market in the early days. Inflation is bad news for everyone really, because it will ultimately cause an affordability issue for everyone who owns a mortgage (see: the majority) and will eventually lead on to a recession if ongoing inflation rises turns out to be true into the future. Let's hope supply chains settle down and Covid does not cause too much instability or even crypto holders will not be safe.
It is true that some crises come out of nowhere and the coronavirus pandemic is one example of that, this is why they call them black swans, however not every single crises is like that, for example the crisis that happened in 2007 that put the financial system at risk all over the world was something that people have been predicting for at least a decade, however those at the top of the financial system and the governments choose to not listen to them, why? Because it was more comfortable and they believed the control they had over the economy was simply too strong.
