Time machine that let's you go back with the two ideal minutes to buy/sell daily

Imagine I could go back in time to the past and were able to trade bitcoin without actually affecting the dynamics of it.
This is imaginary so let's suppose that my trading wouldn't affect dynamically the bitcoin market and that the prices would
still go up and down exactly as they did in the past years since bitcoin inception.
There would be a catch, my time machine would only allow me to carry one information: the best minute
in the day to buy if I was going to buy (with USD) every day at the same minute and the best minute to sell (for USD)
if I was going to do it systematically every day at that precise minute.
From then on my life would be simply selling all my bitcoins (for dollars) every day at a precise minute of the day, I mean at exactly the same time
every day, and then to buy as much bitcoins as I could (with those dollars) at the precise (minue of the day) time that would be maximizing my
profit.
My question is, if I could do these two trades every day at these two precise minutes of the day that would maximize my profit, given that
I would know what exact times I should use - if I had to use the same precise times every day for my two daily trading transactions - what would be
the two precise minutes, the one for buying and the one for selling that would maximize my profits, and how much bitcoins/dollars would I have today if I started trading since the first bitcoin exchange and initial price.

Actually would be fun to have a web app with an algorithm that would calculate and keep updating these values (best minute to buy, historically; best minute to sell; and accumulated balance) keeping a log so that you could go way back to find those values for any previous date and time.

Let's assume that you would start with one dollar ($1 USD). A web app could actually allow you to set the initial value and figure the resulting
final balance with that starting value.
Let's also assume that we get consensual on averaging the values for the bitcoin price on different exchanges and get therefore to base our calculations on the same averaged historical values!

Example:
before entering the time machine you are given one dollar and are told:
'buy bitcoins (with all your dollars) every day at 2.35pm (London time)
sell all your bitcoins (for dollars) every day at 9.47pm (London time).
Come back to this time and we expect you to have... this fabulous amount of: ... x? ... BTC/USD!'
