please keep in mind that
1BTC + 1BCC worth $1,000 is not as smart as 1 BTC worth $3,000...
BCC is a scam, it is almost sort of "pre-mined" by Bitmain (hash power and 1st move advantage), and was only created to enrich Bitmains' greedy board.
Too bad, beacuse the idea of a way bigger block size is great and that is what BTC needs (up to a certain extend, to keep the "decentralized" idea, even if 1% of holders have 69% of BTC...)
Bigger blocks are good only for the cartel
And they actually lead to heavier centralization so it is hard to guess what you might mean by "keeping the "decentralized" idea". Bitcoin needs faster and cheaper transactions, and I don't really think that making blocks bigger serves this purpose very well. More centralization means more mining market monopolization, which is synonymous with higher fees and slower transactions. What we need are approaches that essentially take miners out of the equation altogether (as a factor to count in). Conceptually, it is the PoS model of achieving distributed consensus (instead of PoW, as of now). More specifically, it is approaches that make possible close to real-time, off-chain transactions with low or no fees. Sorry, but bigger blocks don't cut it in any of these departments
