Now I am really interested in understanding your context using the word 'size'.
not just functionality. This is definitely a security feature. This helps maintain the decentralized transaction recording process in the blockchain
It's not the number of people holding bitcoin. It's Bitcoins enormous hashrate. The attacker would have to hijack 51% of the hashrate and that is simply too costly as he needs the hardware and electricity to produce that 51% of the current hashrate.
In theory, some people claim that more than 51% of all hashing power is already controlled by miners from China.
It's the game theory that's securing the network. Why would they endanger their position, by being thrown out of the network, by an army of full nodes for a double-spend?
Yes this is true.
No debate? I'm disappointed.
I think this is one reason why there is an attack on Bitcoin in USA. The Trump administration doesn't like it probably because of this reason. It's not very patriotic. Bitfinex and Tether are run by a Dutch guy who lives in Hong Kong. Blockstream's British CEO Adam Back lives on Malta and the parent company AXA group is a French insurance company. So the main players with Bitcoin seem to be scattered around the globe in different tax havens. Monero however had the ASIC resistance going on. China is the only country in the world that manufactures ASIC miners, so I think the purpose there was actually to block China from becoming a majority hash contributor to Monero as well.
Who said that Bitcoin was supposed to be for the U.S PRESIDENT, and for the U.S. GOVERNMENT? The honey-badger don't care, and the Fed's Brrr printing of $6,000,000,000,000 will play a part in Bitcoin's path to 6 digits.
Nobody said that, but It's obvious that it's a globalist plan to subvert national institutions. Also from my libertarian P2P, decentralization and digital rights activist point of view it's actually not very adequate.
