I guess, the most prolific advantage associated with Bitcoin is due to profits that will be made after some while of investing, i strongly believe that lots of Bitcoin holders/investors hardly would have accepted Bitcoin or become part of the community if it was just alone other advantages like you mentioned. All being part of the benefits, i so much love making profits and i consider it the best i can get from participating in Bitcoin, if truly we can give our honest review mine won't be far from others.
I am very much sure that we holds our holding confidence of Bitcoin on speculations which may also drive mind weakened holders to FOMO.
