I'm a fan of the network marketing business model, but I'm not here to say that they're all great. Some are great and are a wonderful opportunity for people willing to work, but some are straight up scams.

If a company promises financial returns, run. There is absolutely no way that profits can be guaranteed unless you're an employee at a company. In a network marketing company, you're not considered an employee. You're an independent contractor that will only be paid commission off of your efforts.

Both traditional businesses and legit network marketing business have a pyramid structure. But the problem comes when we compare traditional businesses, legit network marketing businesses, and scam network marketing businesses. All three have money flowing up to the top of the pyramid structure. But in a traditional business and a legit network marketing business, value is flowing down. This value is in the form of a product or service. In a scam network marketing business, there is no value flowing down. There is no product or service in the business. If there is no value going down to the end consumer, it is a scam and therefore a pyramid scheme. A great way to know if a network marketing business is legitamite in the USA is if they make you sign the usual IRS commission paperwork (1099). This means that you're an legal independent contractor of that company and will need to pay taxes on your earnings. A scam business won't do this because they don't want the federal government to be involved.

There are many more things to look out for when you're apprached about a network marketing company. I have seen many bitcoin network marketing companies and they have all been illegal scams. I don't know if BitClub is one of those, but all I can say is to be careful. Do your research and know what to look for.
