Financial crises tend to negatively affect speculative and investment assets, so common sense says that applies to Bitcoin as well. The question is, how much will it affect Bitcoin? Nobody here knows for sure.
Well I don't know about this. Last crisis was started by the housing bubble burst and yet, despite the crash housing markets are still getting inflated worldwide. Like nothing happened, investors seem to be oblivious to prior events.
I think you would agree that housing market is at the same time speculative and an investment asset, as such simply contradicts your commonsensical hypothesis. I track a few very successful, classic traders and they tend to agree about the role of cryptocurrency in modern trading. Safe haven they say, declaring about 30% of the assets to be secured in crypto. Thus my feelings about the upcoming difficulties are rather optimistic, if their declarations are real and common, stabilisation for crypto markets may be expected.
