Would you put a small amounts of your savings each month into bitcoins ? That would be a strong signal if everybody started to do this.
How much would you put in % ? I am quite confident to put 10% and raise it slowly from here.
It is a good idea that you save some money each month for you to invest in bitcoin. If we are talking about the percentage of money that you will save for your investment in bitcoin, i think it depends to your monthly salary and expenses. Some people have only enough monthly salary to pay for their expenses and they will not have excess money to save for bitcoin. I think if they are going to save money for bitcoin, they should keep as little money as they can every month that should not affect their monthly expenses.
