You are right - it is impossible to predict the future of the bitcoins. Therefore, we need to use what is now. Bitcoin is a good product and you can make money on it. MLM is very developed on the basis of bitcoin. There you can make good money
Wouldn't it be a shame for something which value is based on its utility to just be used for a scam like MLM. Sure you can make good money from MLM, but only if you're going to scam tons of people. It's not just going to be 10 people but hundreds of them. MLMs have been there long enough for people to be aware of its mechanics and help themselves from getting persuaded/manipulated by some guy.
There's tons of opportunities in the bitcoin world and I'd like to say that MLM is one of the worst ways to earn money.
