you are assuming that all 16million coins are ALL on an exchange and ALL being traded to ALL add some significance to the market value..
No, I'm not assuming that all coins are on the market, but the share of coins that are gained by miners are now significantly less in relation to all coins available.
I never said that miners have no influence on the price; just that events tied to mining are a lot less influential now than they were when the total coins available were under, say, 5M.
Miners need to sell their coins to cover the costs of mining. They have an incentive to sell rather than hold-out for some potential price increase...this incentive to sell their coins only increases with halving.
im sorry but on average only 10k to 100k volume(per exchange) is moved per day and is usually based on about 3k-30k of real coins being moved a few times a day to total the daily volume.
Sure, and any price jump on such low volume is going to be a temporary spike and not a new normal. BTC have gained roughly 50% over the last year, meaning 12 months before today. I don't see halving as a catalyst for any major shift up or down, but if there is a shift due to halving it's more likely to be down than up.
so the reality is that the bitcoin price of all 16million coins is not based on the trades of 16million coins per day.. but usually less then a hundred thousand coins..
remember not all 16million coins are on exchanges.. no where near that many. so when you realise that it is only a smaller amount contributing to the market value, then you see who is hoarding the majority of that market making value.. you will see that pools do have the power to move prices, should they be motivated to.
It doesn't matter if the coins are all traded or not. The point you are missing is the AVAILABILITY. There are plenty of coins available, even if they are not up for sale right this moment. A surge of new bitcoin buyers would drive the price up; but BTC have already reached their critical mass - the point where they can sort of sustain themselves without the need for external promotion.
Gains in bitcoin usage from new users is going to slow as many new users are already participating. A high price per coin will certainly limit the rate at which participants enter the fray, simply based on psychological reasons. The average person is not going to want to pay $450+ for 1 BTC. Even though fractional BTC are available, it's not quite the same as buying 1...there's a reason why companies on the stock market do splits to keep their share prices down.
