If buy price is zero, the division is undefined or the profit is "infinite" because you spent nothing to acquire the asset.
Having a profit of 100% would mean just selling at double the buy price, but nothing stops you at selling at 3x or 4x, having a profit of 200% or 300%.
To give a better example, try with lower and lower "buy price" (approaching zero). You'll see that the profit goes unlimitedly up
I may be wrong, no attacks intended (better to specify lol)
there's many posters that get a lot from reading the posts, they just don't want to open up themselve
Absolutely! What makes this community so lovely is that just by reading posts and comments people can feel heard and loved without the need to write anything themselves.
Tell me it's Photoshop
