Bitcoin transaction deep are very low compared to other industry players like Paypal and wire transfer as well as being fast. For instance, in the latter, they charge up to 3% of the total transaction which is comparable to credit cards. It becomes more expensive when you think about wire transfers. The low transaction fees (son cents) is tied to the size of the blockchain which has to increase in size for the fees not to rise. These arguments about which direction the blockchain size should take have split decision makers in the middle. The blockchain size of 1MB by Satoshi was an arbitrary one. What do you think?
