thanks for the reply brett. it was my thinking too. lately with fees rising rapidly and miners cherry picking transactions, it is a question at the back of my mind, what happens when the rest of the world gets on btc. how long and how much a transaction? privacy is great but functionality has to be considered as well. increasing block size increases speed of processing. it also introduces other issues eg: what is is allowed to be included in block... cost of technology is ever decreasing is a 40tb hdd really a stretch 10 years from now? that allows network to scale over 40. thoughts?
