with the stupid bootstrap process in the current (experimental) implementation of the protocol,
it is not experimental. it is the well tested strong implementation of a peer to peer digital cash that
works safely and is
decentralized.
there are of course other protocols but none have been able to reach the same level of security and decentralization. they have bigger flaws.
Bitcoin started as a pilot project, continued as a fun and became permanent because it is what blockchains do, they become permanent!
It is very inappropriate to brag with bitcoin, instead of contributing to it for fixing the problems and shortcomings, kinda sectarian.
