How could bitcoin in itself be a MLM scheme? Bitcoin is a currency, not an organization where you will get paid for introducing people to it, but it's just that some of the MLM companies have Incorporated bitcoin or altcoins as a payment option. And then there are pyramid schemes.

I guess for most of us speculating bitcoin price is somewhat a tricky affair. People below the age of 20 and above 60 have invested on bitcoins, some of them have studied the bitcoin market thoroughly, gone through the charts, speculating events which might boost BTC price and others are just going with the market flow. It would not be possible to predict an accurate BTC price at any given point in time so in my opinion introducing friends or family to bitcoin is awesome, but let them decide if they want to buy or invest.
