Actually the assumption is impossible. No asset class in history I believe has crashed to a $1 Overnight . Even if it were to crash to a low price it would take many months, maybe years. When a companys stocks tumble because of liquidation it takes months, years too until its delisted.
If on other less regulated market places it did, short sellers could easily arbitrage and for $5 in insurance would buy 5 Bitcoin and run the token into zero value.
your views?
I don't want to assume and I think the thing you say is something that is impossible. Bitcoin is still very much needed by many people and Bitcoin will still have value. 1USD is an impossible value, we'll see what will happen because I'm very optimistic that the price of Bitcoin will increase in the future !!
Bitcoin is an important commodity in the current financial system, a significant development over the past 8 years has made Bitcoin a standard in the financial system at this time.
