I don't think you even need to look that far ahead. If Tx fees haven't reached BTC12.5 per block by the time the reward halves again, BTC is probably dead in the water.
what are you talkingggg about?! that will actually be a really good thing.
tx fees will be negligible PER transaction but if a block has 5000 transactions and packs a nice neglible fee per amount of bitcoins sold it PROVES that bitcoin works well. and keep in mind if bitcoins are worth a lot of money than even 5 bitcoins per block could be worth thousands
I'm not sure you understood me correctly. I think it would be a good thing as well. Your bolded statement is exactly my reasoning behind my bolded statement.
Put another way, within the next four years you will see one of two scenarios: (1) Tx fees will be very, very important, or (2) Bitcoin is doomed to die the slow death of flowers in a vase.
