This might have been answered elsewhere but couldn't find it, if it has.
The miners get paid less and less as time goes on.
With the ledger also growing bigger and bigger, wouldn't the cost of mining start to exceed the profitability of mining? If no one would mine bitcoins anymore, wouldn't it shut the whole system down?
The thing is as time goes on, mining difficulty will increase for certain as more people join to mine, so the reward will reduce as all or most miners as already joined mining pool, also the mining reward do halve in every 210,000 blocks that are mined which take approximately 4 years, this will also reduce mining reward. But,this is reflecting directly on bitcoin not on bitcoin price as bitcoin valuate and increase when compared to fiat, people will still use fiat like dollar to calculate the proc of bitcoin. As the Bitcoin price is increasing, this makes mining still profitable. If bitcoin can continue to increase in price, it will help miners to still gain.
