Yes the return is semi logarithmic and asymptotically approaches 1 million, which can be never reached.There are bots worth around 2.4 Bil (I never could gat one that good...), i did not try with those whether it hist 1 mil flat.
It might as there is also a +/- 5% rando fluctuation of returns and if you hit a +5% day, yeah, it could.
