No, and I have no plans to do so. It would be a very risky decision, even for a well-established technology, such as the bitcoin technology. But I think 25% sounds like a good number.
You need not invest all money into bitcoin ecosystem, but it is highly recommended to invest into bitcoins 90% of your investment networth into bitcoins. This is because of the possible huge returns we may get from bitcoin's future value appreciations. If you have any other options, then you can go less than 90% of total investments with bitcoins.
How can you say that?
How is it "Highly recommended" to invest 90% of your net worth into bitcoins?
In such a scenario, if bitcoin falls down , he will stay homeless for a while, and he won't have any savings, he will probably need to sell his house and move to a cave(jk).
You shouldn't put in bitcoins more then you can afford to lose, it is a very risky investment, so you shouldn't put all of you trust in it , if you have some money to spend and you trust bitcoin, and you think that the price will go higher at the far future, then you should use some of your money and buy bitcoins with it, but you should not use more then 10% of your money as it is pretty risky, unless you are a kind of millionaire or something like that.
