If you ever hear concern trolling about bitcoin's security model (miners stop mining due to low fees and no subsidy) then here's some info to debunk the uninformed, garbage takes.

When a bitcoin transaction is created and sent, it is stored in what is called the Mempool. This is like a waiting room for transactions to be confirmed, also known as mined. Bitcoin miners are in the business of being awarded what is called a block subsidy and the fees from transactions. The block subsidy is new Bitcoin that is awarded, on a predictable schedule, and in fixed amounts. This amount is cut in half after a predetermined amount of blocks are mined and will continue to be cut in half until all of the Bitcoin supply is released. Fees are collected from transactions and circulated back into the economy. This chart shows a representation of what is happening to the amount of Bitcoin miners receive: https://mempool.space/graphs/mining/block-fees-subsidy#all

The first thing you may notice is the amount of Bitcoin being awarded is going down - a lot. This is by design. Everyone mining Bitcoin knows the newly created amount will run out one day. So when that happens, everyone will quit mining and Bitcoin is dead, right? Let's see if that makes sense.

On the chart linked above, take note of the fees, even during times when they are small amounts. During these periods, miners may take in 0.07 bitcoin in fees per block, or as low as 0.03 bitcoin on a regular basis. If the network is not busy, the mempool can even be completely cleared of transactions, which means no Bitcoin collected from fees at all! This is generally no big deal when current block rewards are 3.125 bitcoin each. The fees are a nice bonus, but they don't make or break bitcoin miners as of today.
