Let's see if Veeky Forums is good at basic math.
Say we have an asset that's 100 dollars on day 1. Now, every day, the price can either go up with 30%, or down with 25%, and both price movements have the same probability. What's the return after 4000 days?
0?
It depends, anything between 0 and 59348429003252308012834107202943920995257834690948195302156515900662637463168195

U are a realy stupid idiot.
(OP)
>What's the return after 4000 days?
You can't calculate the return because in some scenarios your asset will go to zero and stay there, which is counter-factual. The best that can be done is to calculate an expected rate of rate based on a series of test cases, something akin to a Monte Carlo analysis.
But, I'm not doing your summer school homework for you, so do the math yourself.
>which is counter-factual.
But it isn't. Pay good attention to the price of Trumpcoin in the following months if you want an example.
Shut up coinfag.
Anywhere between 0 and 100(1.3)^4000
Also, if for some reason the up down movement happened same amount of times
100((1.3)(0.75))^{2000)
Which basically ends up at 0 anyway
