What halving is really? How does it affects the price of bitcoin?


For the first four years that Bitcoin existed miners were paid 50 Bitcoins per block.  Then after those four years the amount paid to the Bitcoin miners was cut in half to 25 Bitcoins per block.  This was the so called "first halving" now after the second four years the amount paid to the miner is scheduled to be cut in half again, this time to 12.5 Bitcoins per block.  This is the second "halving".  By design the amount paid to the Bitcoin miners will be cut in half about every four years until the year 2140.
