Bitcoin is already failing as a payment system.
Big blocktards don't understand that Bitcoin was never ment to be payment system. it was created as electronic cash system!
Bitcoin: A Peer-to-Peer Electronic Cash SystemEvery payment system is created on top of a cash system. You can have many payment systems on top of a single cash system! If we constantly increase block size we shall never create environment where creating competitive payment system is economically feasible AND more importantly in the end we shall ruin bitcoin as cash!
Right now it is not the block size that needs to be increased. It is the tx fees that need to be increased!
