I'd hate to say but the problems listed are real. There is a fundamental flaw in the design, and it was actually pointed out 2 years ago and completely ignored by the dev. Of course with millions at stake for them it's in their best interest to ignore it. Hell, some kill for less money. Do your due diligence people and don't follow fanboys blindly. As far as I'm concerned right now I pretty certain there is 0% chance XRB will replace BTC. You may speculate and you make still make fortunes on the price, but don't fool yourself of the end result. This is not something that can be just fixed. Sorry.
You literally posted this exact same thing just a few pages back (might have been one of your sock puppet accounts). The "flaws" have been addressed numerous times by the dev - nothing but FUD.
To summarize:
The dev was a software engineer at Qualcom, you are a piece of Bitcointalk trash.
To think that some salty teenage third worlders have found some fatal "flaw" that the Raiblocks dev missed is beyond laughable.
Anyway, as you can see by the price your pathetic FUD attempts are rightfully being ignored by the community.
