In my opinion, the barriers that prevent many individuals from investing is lack of source of finance to maintain a consistent trading.
I know that many people want to invest in bitcoins or trade them, but they don't have enough budget to get started. On the other hand I think you can start in a simple way, like saving first from your income and after you have prepared a budget then you can invest.
If you are consistent in this way, then you will probably have more bitcoins in a year or in a few years if you have known for a long time. Another problem is sometimes not about the budget, but it can also be because of their doubts about their potential and their fear of loss. I can say that if you can't invest in high-risk assets, then it might be difficult for you to decide to invest earlier than someone else.
