The issue is scaling fees and transactions.
2025 block of 3.125
2029 block of 1.5625
If transaction never rise much past 450,000 a day

what will fees be.
if 450,000 x 0.0000100 = 4.5 btc this will not work well in 2025 since that 4.5 is spread over 450 blocks or fees of 0.01btc per block
if 450,000 x 0.0001000 = 45.0 btc this will not work well in 2025 since that 45 is spread over 450 blocks or fees of 0.10btc per block
if 450,000 x 0.0010000 = 450 btc this gets closer since that 450 in fees is spread over 450 blocks or fees of 1.00 btc a block
at 20,000 a coin a 2025 block is 3.125 + 1 = 4.125 coins or 82,500 and a standard transaction will be about 2 dollars.
I don't think 2 dollar transactions will sit well as the low end transaction number.
we need to be able to have 2,000,000 transactions daily for the 2029 block size of 1.5625 coins.
People will leave btc and move to ltc as fees are cheap and network is secure.
Well I don't worry for 2020 , but for 2025 or 2024 then 2028 or 2029 I see problems.
I tell you what bitmain and canaan are worried for 2020 since they are rushing 5nm out so they see a blood bath coming at the ½ ing.
Why would you improve the s17 pro which simply kills everything there is?
You fear the ½ ing and want to keep far and above everyone in the game.
The ½ ing and the 5nm announcement has influenced me to not buy any gear until February or March.
