Re:<"Can you please elaborate on what is meant by a "preliminary" loan?">
Scam companies put out a boatload of press releases which sound great. They put in a lot of effort into wording their press releases to mislead, such as giving the impression that the event has already taken place or is "as good as" complete such as by saying, "announces" and "secures." If you look at what the press release 'technically' says, it didn't say they already received $15 million. It may just be preliminary...with a possibility that it might (and often does) fall apart.
These scam companies seem to write this way in the hopes that they can talk their way out of that if it ever gets to court. If there seems to be an abnormal effort to 'wordsmith' the press releases, you can bet it isn't what it appears to say.
Of course the Safe Harbor rules of the Private Securities Litigation Reform Act specifically exclude penny stocks--even though penny stocks invariably cite the act on their press releases in the hopes of warding off litigation when what they say falls apart. If any shareholder decides they want to sue for something that was promised but mysteriously fell apart, they can sue and generally have a good case.
Yes, I understand your penny stock also is the real deal, created with the inventiveness of Edison and destined to be the next Microsoft. Yes, I understand that the delays are also only because your company is making their product even more revolutionary.
