We will be 60 years old and we will still be debating how to scale bitcoin. Franky1 and jonald will still be saying how segwit is bad, and kwukduck will still be FUDding on the price and shilling whatever alternative is being proposed (BUcoin, Classicoin, othercoin)
Meanwhile BTC price will continue going up and so will the fees. BTC will continue working.
I just hope the fee never becomes so high that people can't even move 1 BTC!!! that would be stupid.
But as long as the price goes up the fees will go up too.
The question, when does bitcoin become useless for us? when do we dump because the fee will become higher than our holdings?
I think when you can't even move 1 BTC per coin because the fee is higher than 1 BTC, the price must be super high or it will collapse.
