i would just tell them that it is the best investment option possible at the moment and that it can give a lot of money if they are willing to invest into bitcoin some money
Yeah that would be a good introduction. Telling them it is an investment first. But we got to be careful on how to explain for people are getting scared of different kind of investments. There are scams that are scattered so they will somehow think about it.
telling them it is an investment, will not benefit anything, as a lot of people are scammed by a number of ponzi schemes and with they will consider it as ponzi also, we have to tell them that it is an internet currency and have to tell them that the price of this currency increasing much faster, with that they will invest there.
