What is Bitcoin halving?
Bitcoin halving is a process that is built into Bitcoin’s code, and it occurs once for every 210,000 blocks mined, roughly every 4 years. The process affects how much of a reward miners receive for validating new blocks of transactions on the blockchain. Miners play a crucial role in preventing fraud and maintaining Bitcoin’s unique system of checks and balances. In other words, the work miners do helps make it possible for us to securely send and receive peer-to-peer transactions, instead of having to trust a third party like a bank. Miners are motivated to continue participating in the Bitcoin network by the rewards they earn for validating new blocks. The reward for mining first started out as 50 BTC per block until the first halving event occurred in November 2012, which cut the reward in half to 25 BTC. The second halving is on course to happen on July 9th, 2016, and will cut the reward to 12.5 BTC. The final halving will take place in the year 2140.
Why is the miner reward decreasing?
At first you might think that it is counter-intuitive to decrease the miner’s reward, but there’s a good reason for it. Unlike most national currencies we’re familiar with like Dollars or Euros, Bitcoin was designed with a fixed supply and predictable inflation schedule. There will only ever be 21 million bitcoins. This pre-determined number makes them scarce, and it’s this scarcity alongside their utility that largely influences their market value.
When bitcoin was first created there were very few miners participating on the network and they were originally rewarded with a bigger amount. Over time, bitcoin has become adopted by many people increasing the global competition in mining. The increase in demand for bitcoins combined with a decreasing block reward has a tendency to push upward price pressure on the value of Bitcoin. The halvening is a rare but predictable event in the bitcoin community.

If you really want to get in on the fun, there are meet ups happening all over the world as part of Halving Day; here’s a partial list. Many in the industry speculate that the halving may be one of the reasons for the recent price fluctuations, which we’ve covered extensively each week in our news recaps.

We also discussed the halving countdown using our API in November of last year, where developer Kyle Honeycutt used the API to create a countdown clock to calculate the amount of time left until the bitcoin block reward halving happens in real-time.
Upvoted you
I remember the last halving , there was a lot of DOOM and GLOOM , but in the end it was a positive , and this will be the same , Bitcoin is maturing everyday and become more accepted in the wider public and showing itself to be of serious value , not only money wise but tech wise ..
