As someone with a basic Comp Sci understanding of crypto currencies could someone explain to me why there is a scalability problem? I thought one of the primary benefits of Bitcoin was that higher transaction fees will attract more miners and ergo the transactions can be processed at a higher rate. Why won't this problem be resolved naturally? Tinkering with the block size makes sense to me as a way to crank through more transactions per mined block, but again, why is it even a problem? The mining power is just not there?
