Some people says raising Bitcoin block size hurt decentralization because it increases cost to run a full node. Bitcoin block size limit remains at 1MB 4 million weight units in past few years, while hardware and internet continue growing. The growth could be higher speed, higher efficiency or lower cost. With that in mind and ignoring other factor (such as blockchain size growth, hashrate distribution and total of full nodes), does Bitcoin become more decentralized over time?
P.S. This is just my shower thought, so obviously it has flaws.
You have to do nothing , but observe the past ~11 year history of bitcoin.
Blocksize is irrelevant in the discussion.
Centralization is and already has occurred , limited mining pools only 3 or 4 have over 51% and have had over 51% for years.
The second ASICS were invented and the little guy was pushed aside,
decentralization died.
