Bitcoin's technical problems are that it fundamentally does not scale. If each node has to verify all transactions that is not sustainable in the long term. Hal Finney knew this way back: https://bitcointalk.org/index.php?topic=2500.msg34211#msg342... "Bitcoin itself cannot scale to have every single financial transaction in the world be broadcast to everyone and included in the block chain. There needs to be a secondary level of payment systems which is lighter weight and more efficient."
