Lots of people are starting to be interested in investing in bitcoin and getting away from investing in stock markets. To convince someone to invest in bitcoin is a bit complicated because most of them have a bad idea about it. The first step is to explain that bitcoin is not an illegal thing. Then you show him the  potential of profits he can make by investing in bitcoin.
Bitcoin is still not legal all around the world, that's why some investors hesitate to get in bitcoin business, but that can change if you know how to talk to them.
