(point being whether LN exists or not. if bitcoin fee's are $30+ a time, the amount of people using bitcoin daily declines as do those users desire and need to run fullnodes daily)
Ethereum fees are more than that and the amount of users increases. So, I guess it doesn't work exactly like that.
Yes the market doesn’t work that way, because if the market really works as some people thinks that it does, then by now there would have been a really huge change in the market. A lot of things would have changed by now and there would have been a lot of cryptocurrencies that would have overtaken the top cryptocurrencies such as Bitcoin and ethereum.
Bitcoin and Ethereum have had this issue of having a high transaction fee for quite a long time now, and there have been a lot of other options that have been provided in the market that offers lower transaction fees and also a faster rate of transaction.These alternatives were believed to overtake the major cryptocurrencies as soon as they came out, but this never happened. So that goes to show that this is not how it works in the market and you are right for that, 100%.
