Bitcoin miners’ debt rose from $2.1 billion to $12.7 billion in simply 12 months as they race to satisfy the calls for of synthetic intelligence and Bitcoin manufacturing, in accordance with funding big VanEck.
With out continued funding in trendy machines, miners’ share of the worldwide hashrate will decline, leading to a decline within the share of Bitcoin (BTC) granted every day, VanEck analyst Nathan Frankowitz and head of digital asset analysis Matthew Siegel mentioned Wednesday of their October Bitcoin Chaincheck report.
“We name this motion the ice-thaw drawback. Traditionally, miners relied on the inventory market moderately than debt to cowl these excessive capital funding prices.”
“This is because of the truth that miners’ revenue is nearly fully depending on the speculative value of Bitcoin, making them troublesome to underwrite. Importantly, fairness tends to be a dearer type of capital than debt,” Frankowitz and Siegel added.

Crypto miners transfer into AI
Because the halving in April 2024, when mining rewards will probably be diminished to three.125 Bitcoins, extra Bitcoin miners are diversifying their revenue sources by shifting power capability to AI and HPC internet hosting providers, hurting total profitability.
“In doing so, miners now have a extra predictable money stream backed by multi-year contracts,” Frankowitz and Siegel mentioned.
“The relative predictability of those money flows permits miners to make the most of the bond market, diversifying their revenue from Bitcoin’s speculative and cyclical costs and reducing their total price of capital.”

Frankowitz and Siegel mentioned miners shifting their focus to AI and HPC internet hosting isn’t a risk to the community’s hashrate, as “AI’s prioritization of electronics is a internet profit for Bitcoin.”
“Bitcoin mining is a straightforward method to shortly monetize surplus energy in distant and growing power markets, and may successfully subsidize the event of knowledge facilities designed with AI and HPC transformability in thoughts,” they mentioned.
“Moreover, AI inference experiences cyclical calls for all through the day based mostly on human exercise.”
Miners in search of methods to chop prices
On the identical time, a number of miners they spoke to for this report mentioned they’re in search of methods to monetize extra energy capability at a time when demand for AI providers is low.
Frankowitz and Siegel mentioned this might enable miners to offset or remove costly backup energy sources similar to diesel mills.
“Though that is nonetheless conceptual, we consider it represents a logical subsequent step within the distinctive synergy between Bitcoin and AI that may result in higher effectivity in the usage of each monetary and electrical capital.”
