Coin fees

We all know that when we need to make transaction from our wallet, we need to pay some amount that is known as network fee. Sometimes this amount is small and other time it may be in significant percent from transaction value.

So, who gets this fees?

Network fees goes to the miners. It is reward for contribution to build secure blockchain network. Transaction fee is part of block reward, with other part of reward that goes for new mined coins.

Block rewards are decreasing every 4 years by half, so that means transaction fees are important asets for miners and for the healty blockchain network as well. This means that increased number of transaction will attract more miners, which get more profit.

This model give us following scenario: that longer one coin is mined (his coin age) transaction fees become more important, so we need significant number of transactions. If we need bigger number of transactions to keep healty blockchain network, then with increasing number of transactions we make blockchain network robust as well. Robust because we have to maintain full nodes that make validation of these transaction and that means bigger blockchain database that need to be shared between the full nodes.

Does that means that specific coin network as it ages will be 'owned' by the private companies or it vanishes?
