If I have enough extra savings that is not alloted for emergency then I will choose both cash and bitcoin.

But for now I am saving cash for my kids so that when emergency knock we can withdraw it easily because being a parent is not that easy. Cash is more easy to get unlike bitcoin that we need to consider the price before we transact to have our investment.

Also my brother told me that if I will be given a chance to choose investment, he recommend the bitcoin if my main goal is to have a lot of money but if it is for long run I can invest also on real state and on the stock market. Because he is already doing it  now.
