It's true the max theoretical increase in the first year would be 7x, but the next year would be a max of 2x, and the next could only increase by 50% and so on. However, to reach the max in the first year: 1) ALL blocks would have to be 100% full and 2) transactions would have to increase at the same rate. We'd have to be doing 2.1 million transactions a day within a year to make that happen, and would therefore need blocks to be that big. Realistically, max block size will grow (and shrink) at a much slower rate ... even more so with SegWit. > The main problem with this proposal I think is that users effectively have no way to stop the miners from increasing block size > continuously. Yes they could, simply by not sending transactions. Users don't care at all about block size. They just want their transactions to be fast and relatively cheap. -t.k.
