Personally, I support the
spin-off mechanism for launching new experimental alt-coins. Bootstrapping the coin with a Blockchain-based initial coin distribution
Your one world currency, Bitcoin dictatorship model is not in the best interests of the public, traders, or virtually anyone except a small percent of Bitcoin holders, so there's little reason for anyone to support it. All it does is reward dumb money investors.
No matter how strong bitcoin is, I think it is VERY dangerous to put all your eggs in one basket.
That said, I think side tree's are a great idea for Bitcoin, but should not be the only game in town.
The more decentralized the overall structure, the more powerful imo it will be.
I see a future where Crypo's can organically connect and mingle with one another, much like a side tree/chain anyway.
