At least, I very much doubt that bitcoin can rise from the current price to $500k or $1 mln in just one month.
Obviously not likely but thats how you get the odds times hundreds. Its not impossible an event can occur in one month, this case wouldn't be about crypto itself exactly. I cant think of what giant advance might take crypto that far forward, India declares BTC its national currency perhaps would be the size event needed.
Whats more likely is dollar melts down in that particular month, somebody notices they dont have a serviceable debt schedule and the majority of the trade balance is propped up by the trading of that debt. Its not likely at present but sovereign debt crisis can occur as Greece demonstrated a few years back, their hand was forced by inability to buy their own debt but writing a cheque to yourself is nonsense as a solution yet market accepts this at present if that changed then you get wild prices in anything including BTC.
