IMHO it is irresponsible to put all your wealth in BTC if you have anyone else relying on you such as a family.
This over and over. The thing is, one can argue BTC is not a currency at the moment, yes more and more each day people are accepting it. But I can't go to the grocery store with my bitcoins, and provide food for my family, I need fiat for that. I can't pay the Chucki cheese I go to in BTC, nor schools or anything like that.
Plus, if I have everything in there and sell BTC to get fiat each month in order to pay bills, if a 51% happens and pretty much ruins everything. All of my work goes down the drain....
