並非所有礦工都能幸免於降低成本的比特幣

比特幣應該花費多少才能令礦業再次獲利?

一個 70% 12月中旬比特幣價格的下跌實際上降低咗採礦的回報率. 同今日和 #8217 的價格水平, 降到最低 $ 6,048, 只有最大嘅礦工才能維持生計. But the analysis of Bloomberg shows that even among the major players not all can survive.

今日, 67% of the mining-energy is concentrated in the hands of four pools: BTC.com, AntPool, SlushPool and BTC.top. But Bloomberg analyst Tim Kulpan asserts: “If you are not the company that manages the fastest mining installations purchased at wholesale prices, then most likely you are losing money.” December’s rise increased the mining market by 40%, which led to an imbalance of the system: according to Blockchain.info, it was 51% harder to extract the block.

Has grown both the complexity of calculations and the amount of energy consumed. If bitcoin stopped at a 50-day moving average of $ 13,200, then with the current complexity and number of hashes, the average miner with good equipment would receive $ 80 per week (but the older the equipment, the lower the profit). 然而, even the most advanced bitcoin-mining installations do not protect against the risk of losing funds, when the price drops sharply, and the miner stays in the network: the miners suffer losses starting at a price point of $ 6,800.

If the price does not rise, then the average miner will lose $ 3 per week. Mining pools, such as AntPool, can remain in positive territory, but their profit will be 90% lower than with a 50-day moving average of $ 13,200.

Tim Kulpan modeled the only, 在他看來, situation, in which the mining will again become profitable: the growth of bitcoin with the mandatory release of a part of the miners from the game in order to reduce competition. The analyst is sure that all today’s participants will not be able to avoid losses: either someone will free “the mining ship” from its weight, or everyone will drown.
