- Bitcoin miner inflows to exchanges hit over $1B daily, raising concern among investors and traders.
- CleanSpark and MARA continue expanding operations despite rising sell pressure from other miners.
The amount of Bitcoin sent by miners to exchanges has been raising eyebrows lately. According to data from on-chain analyst CryptoOnchain at CryptoQuant, between May 19 and 28, 2025, the inflow from miners to exchanges hit an insane figure: over $1 billion per day. Such a figure has never happened before and is enough to make many traders think twice before going long.
Bitcoin Miner Behavior Splits Between Selling and Strategic Holding
Interestingly, this massive spike coincides with the Bitcoin price tending to stagnate or even start to weaken. This means that the selling pressure from miners is really being felt. When the inflow from miners’ wallets to exchanges increases drastically, it usually means that they are ready to release their BTC holdings to the spot market. And when supply increases amidst lackluster demand, well… we know where the price is headed.
However, there is another side to this story. Not all miners are rushing to sell their assets. Some are taking the opposite approach. Take CleanSpark for example. The company even increased its Bitcoin holdings to 12,502 BTC as of early June, and has not sold a single share since November 2024.
Not only that, they managed to mine 694 BTC in May and are targeting a hashrate increase of 50 EH/s this June. If achieved, CleanSpark will be the first public miner to reach that level with its own infrastructure.
MARA Holdings Doubles Down With Bigger Wins
On the other hand, MARA Holdings has managed to produce 950 BTC in May alone, up 35% from the previous month. The number of blocks they won even reached 282 blocks, the highest since the April 2024 halving. They now hold a total of 49,179 BTC. This is all possible because they run their own mining pool, namely MARA Pool, which makes operational efficiency and control much more optimal.
Even so, the surge in inflow from miners is still a strong signal that cannot be ignored. Not only traders, but also big investors must be wary. Because when miners—who by the way have a lot of their own Bitcoin production—decide to start releasing their stash, it means there is a pressing concern or need driving the decision.
Looking further ahead, the CNF previously reported that an estimated 70% of Bitcoin mining activity will be powered by renewable energy by 2030. And that’s not just wishful thinking. The road to that point is already visible. Since 2011, the proportion of green energy in Bitcoin mining has risen from 20% to 41%.
So, while we’re being treated to news of selling pressure today, not all miners are moving in the same direction. Some are building and holding on, while preparing for a greener future.
Besides that, as of press time, BTC is changing hands at about $105,145.92, up 1.35% over the last 24 hours, and its market cap is back to above the $2 trillion mark.
