Thats because its impossible to prove a negative. One can not prove that there is NO hardware, just like one can not prove there is no teapot orbiting the sun or that unicorns do not exist. Its trivially easy to prove the positive if its real though, so the burden of proof lays with the claimant, in this case, the cloudmining service that claims to have the hashrate they are selling.



I agree . But in the other sense than you meant it. If cloudmining services offer less proof of their legitimacy than there is proof for unicorns, Id rather stake my money on the existence of unicorns.


Bitcoin by itself is already risky and potentially lucrative enough. Trying to invest bitcoins makes as little sense to me as trying to invest gold.
FWIW, Ive been around bitcoin for a fair bit longer than you appear to be; in all my time, I have seen ONE bitcoin denominated investment that overall returned substantially more BTC to its investors than it collected (AM). Well maybe two if you count satoshidice, even if that was hardly substantial. . And thats out of 100's if not 1000's of iPO's and investment vehicles and scams of all kind. Good luck spreading your risk in this minefield.
