Nope, I have not did this and I'm also not planning to do this because its not smart and its also that there are way too many risks for me to do this.
Investing all our money in any single product is very risky whether it is bitcoins or any other product. Because if any bad news about that product then suddenly you will lose a lot of money from your investment so it is always good to diversify your investments and reduce risks. I invested in real estate, gold, casino investments, shares and holding bitcoins as well.
