Extremely unlikely. Bitcoin has been around 12 years and it's just now starting to go mainstream. Most people still have no idea what it even is. You can count the number of publicly traded companies that have Bitcoin in their treasury on 2 hands and that's only destined to increase.

I can't give you an actual estimate of how long it will take for Bitcoin to lose its market share but I can confidently say it will take decades. At very least until it replaces a good chunk of gold's market cap.

Seems like an Is/Ought Fallacy. Also, governments won't willingly surrender their control of the money supply. I think that with one stroke of a pen they could let the price /10 as fast as it went x10.

Moreover, since technology is accelerating ever faster, five years from now is a lot longer than five years starting from 1980.
