I was just thinking this morning, about the reward halving upcoming sometime 2016. Most ppl here are pretty assured that when the halving happens it will guarantee that BTC will increase in value.
Those people are fools. It might increase in value, it might decrease in value, it might stay the same. There are far too many influences on the exchange rate to assume that just because the mining subsidy will be cut in half the exchange rate will rise.
There have been plenty of guarantees over the last year or so and none have panned out so far.
Not much of a "guarantee" then, is it? Perhaps you should put a bit more effort into filtering who you accept advice and information from. There are a lot of fools on the internet that will say or believe just about anything.
If BTC remains at its current performance level, wouldn't the halving merely drive any miners operating at a thin margin out,
Yes.
make mining not profitable enough for new miners to get in the game
Perhaps. But if so, then the difficulty will drop and it will become profitable again.
and basically slow the network?
Perhaps for a short while, but if the average time between blocks is greater than 10 minutes, then the mining difficulty will be reduced every 2016 blocks until the average time returns to 10 minutes.
I understand supply and demand, but demand drives that, not necessarily supply.
Then you don't understand it. It's the interaction between supply AND demand that influence price.
If no one wants a 200$ btc, it doesn't matter how many there are or how hard they are to mine?
And if someone wants a BTC and the cheapest one available is $200, it doesn't matter how many people are willing to pay less.
What do you think will really happen when the halving comes? anyone thought through any scenarios?
It's unpredictable, literally. Anyone that tells you otherwise is either lying to you or doesn't know better.
Of course, we have had a halving in the past and we seem to have survived it. Perhaps we will again.
