I thought you came here to list all the reasons why we should not buy bitcoin with your title and I was so ready to hit you back.

If you are happy with the way the traditional banking system has been working, the way you have been enslaved all these while, do not value your financial freedom and you are scared to take a little volatility risk, then bitcoin is obviously not for you.
I guess I just listed the reasons you should buy after all. Anyone who is looking for reasons not to buy bitcoin in the first place rather than looking for all the benefits blockchain technology brought with it, then they had rather just stay away.
