Miners can profit by selling their coins at a profit if their mining cost is lower than the market price of Bitcoin and they can hold the coins.
When a miner's Bitcoin mining cost is higher than the market price, they need to cover their operating expenses or take out loans.
Which explains exactly why solo mining as a thing actually seems to be declining. When both price and hash rate competitions put you at a disadvantage you basically run into gross loss. That's why it's still very important we still have price increments from time to time just to sustain cost for small miners.
Risk diversification is the right strategy, but what will these companies do when the AI bubble bursts?
MARA Holdings doesn't purchase the very expensive equipment needed to power its AI systems. MARA Holdings provides land and ready-made energy infrastructure, while its partner, Starwood Capital, invests in construction and enters into lease agreements with corporate clients.
These are all business minded and structured incentives. They are partnering and investing in energy solutions because that's where most of the losses come in. Electricity is getting crazy expensive.
I don't see solo mining in decline right now.
Look at how many solo mining devices are currently on the market and how many pools are popping up.
It's unprofitable, but $200-$1,000 per device for solo mining and a few tens of dollars or less in electricity costs doesn't seem like a loss for miners.
if everyone follow mara that provides land and futures contract its fine but what happen with other companie
