A rise in mining difficulty marked the start of bull cycles in 2013 and 2016, though it remains to be seen whether the coin’s recent rally to within 3% of its ATH price is long-term bullish. The price of Bitcoin fell by 11% last week as many whales moved some of their holdings to exchanges and is $18,122 at the time of publication.

Greater mining difficulty can mean an increase fees for users and the time required to generate a block in addition to increasing the number of unmined transactions in Bitcoin’s mempool. According to estimates from Earn.com, the optimal BTC transaction fee is currently 14,272 satoshis, or roughly $2.60.

The Ethereum (ETH) blockchain has also seen record highs recently. Glassnode reported mining difficulty for the network was at a two-year high on Friday following the price of the token falling from more than $600 on Nov. 23 to $513 in three days. 

The network hash rate — an indication as to how much computing power is being dedicated to validating Bitcoin transactions — plunged following the metric and mining difficulty reaching an ATH in October. Data from Blockchain.com shows the metric fell more than 27% between Oct. 17 and Nov. 2, from 146.5 EH/s to 106.6 EH/s. Bitcoin’s hashrate is currently 130.15 EH/s, according to BTC.com.

At the time of publication, the price of Bitcoin is staying above $18,000, having risen 1.9% in the last 24 hours.
