Do not risk only those people who want stability and do not want to become famous and rich, so I think that the risk is necessary, especially in the fast-growing cryptocurrency market !)
And there are people who choose to get a handful of money and prefer to go home. There are those who prefer to take risk and they are the people who are called as crazy but they are the people who make the money and inspire people in future. So, if you do not take risk, you would stay the same man and might even get your resources faded with the increasing consumption.
