I have said many times that I feel satoshi’s biggest mistake with Bitcoin was not putting in a block size adjustment feature similar to the way difficulty is adjusted. I believe the blocksize limit was put in place as a knee jerk reaction to the chain being spammed and if satoshi had more time on this earth a method to adjust the blocksize limit would have been put in place.
We can't blame him, he couldn't really keep absolutely everything in mind. Sometimes, you discover new problems as time goes by but you are right, it would be the best solution to increase block size two times as reward splits.
What makes BCH and BSV shitcoins is a plethora of reasons other than just having bigger blocks.
People call BCH and BSV shitcoins because they read someone posted shit on them. Actually, they don't know the real reason why these coins are shitcoins. They have probably never heard about Craig Wright, Roger Ver, Jihan vu and others.
I read many posts and to be honest I can't understand how increased block size can make bitcoin less secure. Is 1MB any standard for security?
Also, I want to say that it's not a problem today to store bitcoin blockchain on hard drive. SSDs and HDDs are way cheaper than they were years ago, we have far more speed and capacity today for a cheap price. Please, don't call a problem something that is not a problem. Space and price is not a problem today! Increased block size won't be a problem today! If block size was a problem, someone would come up with an idea to decrease block size in 2015-2016 but no one came up with that idea because that's not true!
But to be honest, after thinking for a while, I think we have another problem besides block size and they are miners. Mining is becoming way centralized, pools are collecting all the transaction fees and people are willing to join pools that don't share transaction fees. These pools are one of the biggest pools who can flood mempool with their resources and gain more profit. They can flood it easily because they confirm the blocks and fees go back to their pockets but increased block size should make it a little bit hard for them to do.
