This year, the price of Bitcoin (BTC) has fluctuated from a low of just over $3,000 to a high of around $13,000.BTC's mining difficulty, which measures the complexity of the computation required to mine new coins and create new blocks on the network, has increased at an unprecedented rate.
Bitcoin mining difficulty is adjustedapproximately every two weeks to take into account the hashrate of new miners on the network. Despite the fact that the general trend has been upward almost since the creation of the network, short but significant failures happen. For example, in December 2018, mining complexity decreased three times in a row, the total drop was almost 30%.
This calendar year, the difficulty of mining BTCdecreased five times, but not more than 1.18%. This is unprecedented. In no previous year, the most serious drop was so low. In the entire history, at least one drop was more than 5%.
Of course, 2019 has not yet ended, but it is worth noting that at that time last year, the difficulty of mining BTC decreased only once (3.45%, which is more significant than any decrease in 2019).
If this trend continues, it will confirm that the BTC miner community is less sensitive to currency price fluctuations than ever before.
To understand why, it's worth looking at the basicsdifficulties of cryptocurrency mining. The Bitcoin network produces 2,016 new blocks every two weeks. Maintaining this speed is important for network performance. Blocks are generated by miners' computing systems that solve mathematical problems. In this case, it is appropriate to compare miners with lottery players, and the difficulty of mining — with a very low chance for any individual player to win. Every time someone “wins” the lottery, a block is created.
Since bitcoin networks need blocks generated bywith predictable speed, the complexity of this “lottery” should vary depending on the number of “players” (miners). For example, if many miners leave the network, the mining complexity should be reduced, or the rest will not have enough power needed to generate new blocks at the speed required to maintain the network.
In fact, the Bitcoin mining system is more complicated thandescribed above, however, according to its basic principle, the upward movement of bitcoin this year is a bullish sign. Investors come and go, the price fluctuates up and down, but interest in Bitcoin mining is clearly growing, and this year it has become more stable than ever before.
