The problem with Dash is how it rewards its community. In order to benefit as a Dash owner, you must own a masternode in order to stake (collect crypto dividends and vote). Masternodes right now cost $60k-$70k to own. This means that as the price goes higher, more and more people are boxed out from being able to participate in the systems benefits (owning a masternode, 1,000 shares of Dash). This creates a situation where there is adoption resistance from new users (a user scaling problem). PIVX on the other hand is an improved Dash fork with tech improvements (faster), but also solves the critical PoS issue. Masternodes do exist and receive slightly higher payouts, however, stakers with any investment also get benefits from holding. This seems to be overlooked sometimes so I just wanted to make this distinction clear....and I think this, along with the growing and dedicated user base and developers, is why PIVX can rise past Dash and others in time and claim the title of most used payment system.
