I think it is wise to keep an ear to the ground for other ground breaking technology, but IMO, safe net is the most ambitious project our there, combined with a determinded, sincere and qualified team to deliver it. I felt this from the moment I had read the white papers and the Google forum at the time before the crowd sale and still feel it now.
It is obvious that safe net is the life’s work for key individuals in the maidsafe team. Failure will simply not be an option for them. Considering what alpha 2 has already delivered, I see no reason to doubt a fully working final product will be delivered either.
Most of the other projects in this space are either essentially blockchain apps or respins/reimplementations of the blockchain. While these may or may not be successful in then long term, they are also a completely different scope to safe net. They are aiming at a different phase of the technology lifecycle.
Safe net is risky, sure, but with steady progress this risk is deminishing. We should not forget the impact this will have in this space if a fully functional safe net is successfully. A new cluster of second technology phase apps will build on it, there will be clones, etc. It will be like Bitcoin over again to a degree.
Day, swing, etc, trade if you like but there are strong reasons to buy and hold maidsafecoin.
