I think it is a solid portfolio for the long run.  The one that is least likely to be around for the long haul, in my opinion, is XRP.  It is a technology whose fate is tied to that of the dinosaur fiat establishment.  It is likely to do well in the short to medium term, though; I just do not trust it as a long term investment.

XSPEC stands out as the race horse of your portfolio.  It is deeply undervalued, but has some very dynamic developments under right way now, which should raise its visibility, price and ranking substantially in the coming weeks.
