Risk depends on amount really. Just found out an employee of mine is retiring at age 50. He made $500k on a real estate transaction a few years back and put nearly all of it in bitcoin. The dude made around $100k/yr for the past 8 years and is retiring. I am shocked.
I can help with info if you are interested. Been diving into this to diversify even more.
Honestly, it is to the point where I think most anyone with substantial savings, needs to consider.
