Small local financial crashes are good for bitcoin,but a major world crash like the great depression might hit
cryptocurrencies as well.
I don`t think that people will trust a cryptocurrency when the major crash happens.
They will most likely buy gold and silver.
Well if likely there will be a major crash is happening,
I'd rather invest my finances to some business that I think that don't be affected by the crash. If I'll invest in cryptocurrency, just some part of my finances will do as there will no 100% assurance of return of investment. I'll distribute it equally where I think it can have a good output
That would be risky as hell
It is businesses that are going down during major crashes. In fact, this is what an economic meltdown primarily consists in or even caused by, i.e. lowering or outright vanishing business activity. You may think that a certain business may not get affected by the crisis, but this is not so since all businesses suffer dramatically, it is just a matter of degree. That is, some businesses suffer more, some less. And I'm not even speaking that such investments are risky on their own even in the times of economic boom and revival (read you can still easily lose your investments, see the dotcom bubble)
