The Bitcoin block-reward halving is expected to take place mid-year 2020. The halving event has occurred twice before, making the 2020 event a third. BTC blockchain, rewards an individual or a group for validating transactions. A block reward refers to the distribution of the new blockchain.
Halving occurs when the network reduces the reward by 50 percent, which happens at intervals of 210,000 blocks. The intervals are estimated to take place every four years.
Grayscale Investment, a leader in digital currency investing, raised concern that many retail investors lack the knowledge on the BTC block reward halving system. According to a tweet by Joseph Young, investors are not aware of the Bitcoin halving event despite two previous similar events.
