I truely believe while Bitcoin will always be number one there is a need for greater security. Thats why I went all in on Xtrabytes as it seems like the only coin that solves the flaws of POW and POS (51% attack). In time that will be I believe the only thing that matters in crypto ie security. Which is why it is almost a definite top 10 project. I could be wrong but I doubt it.
