I asked companies house two years ago about their registration system (because I was dealing with a hyip cryptocurrency project that's registered there) and they said that any company can register there but they can't guarantee if the company is legit or not.
Is there any other way to make sure that algo trading is a real business?
No, this question isn't an accusation or something, but it has to be asked so potential investors will know what they're putting their money into, because we're dealing with money here and we can't be too careful, right?
Cheers.
