These scams are simply a form of gambling camouflaged as legitimate investments. Most of the schemes or programs do not work as promised and buyers cannot get their money back. In many cases the supplier simply disappears.
Maybe I'm wrong, I don't know
Yup, scammers often do the same thing by offering investment and profit. However, there are many gambling websites that do have the capacity to invest properly. You can find it by doing research from companies, company operations, community reviews or other metric. Don't look for reviews from websites that are not based on community, because most of these reviews are only fictional reviews.
BTW, what the OP said was a betting plan, try to understand that first, this is not investing a money like you think,
