Historically, miners were able to recover from the impact of block reward reduction due to bull runs that followed each halving. As noted by Chainalysis, miners were busy building cash liquidity on the verge of the first two halvings in 2012 and 2016, but this was not the case ahead of the third halving in 2020. Based on the performance of Bitcoin following the two previous mining cycles, miners waited longer to liquidate their reserves since they were anticipating higher prices.
This time around, the aggregate balance of mining pools has also decreased by more than 20%, but the decline is much smaller compared to the first two halvings. The fact that the price of Bitcoin managed to reach a new all-time high on the cusp of halving shows allowed miners to feel more comfortable liquidating some holdings to prepare for the severe impact of the halving.
A double-whammy
Apart from the Bitcoin halving, miners also have to deal with growing competition from artificial intelligence (AI) companies.
Core Scientific CEO Adam Sullivan has noted that power has become "extraordinarily constrained" in the US.
Tech giants of the likes of Amazon are willing to spend massive amounts of money on data centers. This will make it harder for miners to secure new low-cost power contracts.
