You're paying $5,000 USD for "a magical money machine," and it's = S-L-O-W-L-Y dawning on you that the words which I have enclosed in [[ = double brackets ]] can be omitted entirely from these sentences. You're being very cleverly suckered. It's as simple as that. And, = you're pouring serious money ( >=3D $5000 USD ) into "the same damn con" = that has been foisted upon "clever, smart" (sic) people, well, since = time began. "Public-key cryptography" is designed around a truly-intractable (so far = as we know ...) mathematical problem.

All of this is = plenty good enough to enable people to sell you(!) these mathematical = one-armed bandits for $5,000 USD a pop. There is no "bubble." There is only: "sucker." " ... and two to take him."
