It could go to zero, or be an absolute grand slam, but the tech is impressive and it has a VERY valuable USE. Imagine FOREX transactions settling in 4 seconds, instead of 2-3 days. It reduces FX risk DRAMATICALLY. That's worth BIG $$$.

As with all investments, hold your core position, sell spikes, and buy dips with the rest...and the beat goes on.
