Bitcoin can easily get 4th if it reaches $125k. Maybe even just $120k, but I didn't do the math.
I think Bitcoin will rather be 5th on the list and not 4th if it's price skyrocket to 125k per BTC. Because I just did the maths right now while using the current Bitcoin market cap as a case study for this, which is currently over
19.79million BTC at the time of writing this post. Hence, for Bitcoin to be 4th on the list, it needs a market cap above $3.3trillion. And the only way that can be possible is with Bitcoin price been value at $167k per BTC
That is; 19.79million x $167k = $3.30trillion
NOTE: We can notice this market cap is higher than
"Microsoft" that is currently 4th on the list as shown below)

Second place should be achievable after $250k.
So lets calculate this to see if it's correct or not while using the current market cap as a case study for this
(i.e 19.79million BTC).
That is;
19.79million x $250k = $4.94trillion
