The 3 trans/per second limit is an inherent limit in the protocol right now. Fixing that is being discussed but will require a fork (and has already lead to a lot of religious warfare). Even after the fork, the requirements of supporting humongous blocks just to support more than 3 transactions per second will lead to even more centralization of Bitcoin than what's already happened, as full nodes are forced to move onto server-grade hardware instead of an actual decentralized swarm. You don't trust the USG? Great! But now you have to trust China and GHash.io instead, it's been years since Bitcoin has actually been "decentralized" in any meaningful sense. But even with the low current block size, money supply inflation, and plummeting Bitcoin price, the network has still failed to scale as judged by the only thing that matters: Cost per transaction is still $10, and it would be even more expensive if Bitcoin price ever went back up! https://blockchain.info/charts/cost-per-transaction https://blockchain.info/charts/cost-per-transaction
