Majority of the network marketing gets turned as a scam when the chain doesn't grow further as the expected way. Networking market gives a big return for the top people in the chain while with cryptocurrency one who has the patience and the affordability to invest big at the right time will profit through bitcoin making it better than network marketing.
Exactly like what you said! Network marketing is good for the people who join early, like they will have some many referrals and they will make a huge amount of money, but personally I don't like this field because in most of the cases it turn up to be a scam, so I am fine with investing my money in cryptocurrencies and waiting. I don't like to take a high risk nowadays, because I don't see any clear movements in the market.
