The biggest problem right now facing Bitcoin is the scaling problem. The current debate is between the "small-blockers", which support scaling bitcoin by limited block size increases and implementing off-chain transactions, and "large-blockers", which advocate continuous block-size increases. I personally don't think either method will scale in the long term, especially considering the original goals of decentralized digital cash. It is my opinion that both scaling paths force centralization of the network.
