It's silly trying to predict what will happen after so long since it's very difficult to predict stuff that will happen in the next hour. We shouldn't really be worrying about fees and miners for now since they are in a good place at the moment.
Instead, we should focus on more pressing matters like mainstream adoption of popular cryptocurrencies like BTC, ETH, LTC etc at present.
What a head shaking comment from you hehehe. It should be something that this community should start being aware on. However, similar to what @LongTimeAgo said when he started this thread,
it might be heresy. Why is it heresy? Is it because the question will threaten to stop bitcoin from pumping? I am very skeptical on the attitude of such people.
In any case, there is an increasing number of people who are beginning to be familiar on this question. The answer might be something they might not like.
