Small project yes, but how can this project "be a replacement for bitcoin" while being a small project this late in the game? Nobody has explained how it could even be possible that such a small project that has been around 5 years, a market rank of #300+, 80%+ emissions, and about 10 active social community contributors overtake the top cap cryptocurrency in the world?
It can because there will be an increasingly strong demand for an electronic cash system that offers privacy by default, has tail emission, and is lightweight to process. Neither Bitcoin nor Monero (nor any other coins) satisfy these desiderata.
