比特币 (BTC) 的挖矿难度已达到历史新高，降低了矿工本已减少的利润率。
新的发展对加密货币矿工来说可能是灾难性的。由于 BTC 的价格似乎也在下降，比特币矿工可能会陷入风暴。
根据监测 BTC 挖矿性能的公司 btc.com 的数据，比特币挖矿难度急剧增加。
正如著名加密货币记者 Wu blockchain 在 Twitter 上注意到的那样，挖掘加密货币的难度增加了约 5% 至 31.25T。
两周前增加了大约 5.6%，当时网络的难度首次超过 29T 区域。

比特币挖矿是向区块链确认并添加一个新的交易区块（集合）的过程。难度级别衡量争夺挖矿收益的复杂程度。
参与挖矿过程的网络用户（称为验证者或矿工）对于他们成功验证并添加到区块链的每个交易块都会获得固定数量的 BTC 奖励。

相比之下，比特币哈希率或网络的计算能力几乎保持不变。
然而，在同一两周内，比特币挖矿的盈利能力下降了约 13%。
在此期间，比特币价格下跌了 23%。 Coingecko 图表显示，价格从 4 月 27 日的约 39,390 美元跌至目前的 29,310 美元。
据分析师称，如果加密货币长期徘徊在 30,000 美元以下，比特币矿业公司将面临重大危险。
然而，最大的担忧不是 BTC 价格跌破 30,000 美元，而是下滑的持续时间，或者加密货币将继续下跌多长时间。
根据 ByteTree 发布的数据，过去几周矿工花费的新创建 BTC 比持有的多得多。

与此同时，大多数比特币矿工目前正在转向以太坊，因为随着 BTC 挖矿难度的增加，网络受到严重影响，投资回报率更高。
2021 年，当 ETH 突破 4000 美元阻力位时，以太坊挖矿的利润更高。此外，随着 ETH 2.0 发布的临近，最受追捧的加密资产发现越来越难以保持其主导地位。
随着这些发展的出现，越来越多的矿工正在转向以太网络，并避免在交易过程中出现意外崩溃。
