Once again, you don't know what amount of coins actually enters the circulation and how much leaves (being lost or otherwise done with for all). So your assumptions are no more than wild guesses...
Even if all other factors had been kept constant
I do know how much enters the circulation.
https://blockchain.info/charts/total-bitcoinsI dont know how much gets burned/locked away (but even if this would matter, it gets priced in long term, one of the reasons bitcoin didnt dropped below 150$ is because satoshi has burned alot of coins and he never sold at bigger crashes, so its somewhat safe to say that 100-150$ is a strong price support).
If the miners dump the coin after they mine it, then obviously the price goes down (I know how much gets mined, and I know how much price decreases, so that can be measured).
I dont know how much they hoard, so I was asking you about that, what is your knowledge how much mining pools hoard and how much they sell, this is the big question.I've thought about this (though toward doges). Well, it is possible to write a routine that would keep tract of bitcoin wallets (through the blockchain). I abandoned this idea, since the efficiency (accuracy) of price prediction (which is what evidently is your aim) would be no better than that of flipping a coin (actually, even less)...
In short, you are wasting your time
Not necessarly price prediction, i`m not that interested in bitcoin speculation, since I wont really be selling my bitcoins. In worst case scenario I would move it into altcoins ,but not back to fiat.
Maybe you looked at low timeframes (hourly,daily) , bitcoin has little sample of data, and the trading noise is big, your signal-to-noise ratio is small so you want to look at larger timeframes.
I used to research forex trading bots, but then I gave up the idea, because I realized that financial markets can only be predicted in larger than 1 year timeframes, and the ROI is small ( so forex get-rich-quick trading bots are most likely scams), not in 1 minute charts or silly stuff like that.
With bitcoin you have more data, and accurate data (not central bank lies), so it is possible. Yet we have only 6 year history, so its not viable now.
