I think in this day and age when everything is so unknown, the thought of cryptocurrencies and other forms of the share market can be dawnting for a lot of us. We may not know enough or we may know a lot. Its other people's opinions which encourage friends etc to join and then comes the influx to the market itself. When bitcoin came out everyone was skeptical, now look at it its earning thousands a day, granted it is not without risk, but that's what the industry is all about. You will have to risk seomethign for the reward.
