Sometimes you also need to consider availability of information about bitcoin opportunities to people. Some would gladly invest if they have all it takes: knowledge and technical know how. In a world of evolving technology, anyone would love to follow the trend and not many would rightly reject bitcoin after all they have seen happen in January.
No matter how sophisticated any technology becomes, there would always be a basic knowledge which requires little or no mastery of technology before you can apply it.
Those who have seen the reality in January this year and also in previous years about Bitcoin, I think they will all have a basic foundation to believe in Bitcoin and will also be brave enough to learn more about Bitcoin until they try to become investors in Bitcoin by allocating their money to buy Bitcoin. Especially if there is someone who is willing to give the best advice to those who are new to Bitcoin, of course it will increase their confidence to continue buying Bitcoin and consider it as a fairly sophisticated investment for their own future.
As for the problem of technology and its development, I think it can be understood by reading more about the relationship between technology and Bitcoin. Meanwhile, for the action itself regarding Bitcoin, there must also be those who already believe that Bitcoin is a very good thing and that no one can match it as the best coin ever.
