Diversifying is absolutely necessary for De-risking. I think a lot of people, myself included, expose themselves to unnecessary risk because they got greedy and think "if such and such ICO goes to the money I need to put in more to become really really rich". But the reality is it is a big if. There needs to be some risk involved in order to earn money of course, but there should be some part of your investments in less risky assets. Real estate is a good bet as even if house price drop you still have the tangible asset that can be used or rent out for income.
