April has been a busy month for Bitcoin, as it has reached a big milestone when 17 million Bitcoins were mined. That means there are only four million coins left to mine before reaching a 21 million Bitcoin cap. However, we have to note that it will be long before this figure is reached. This is because, if the protocol remains, Bitcoin's upper limit will be reached in 2140, which is 122 years.
What will happen when the last Bitcoin has been mined. Currently, miners want to get Bitcoin tokens as a reward before the maximum supply is reached. When it has been reached, although there are no longer any coins, the transactions will still have to be validated and stored on blocks in the blockchain, which means that miners can then benefit from transaction fees.
However, this has raised some questions about miners. When all the coins are mined, there will be transaction fees that will become an incentive for miners. However, if the Lightning Network is fully integrated at this time, there will likely be fewer transactions that are recorded daily, which in turn will affect the amount of money you make.
