Yes, I am stunned by seeing the price hike of Bitcoin. Earlier it was not so high but in few months there is a great change. Due to high prices many people got interested about Bitcoin and start investing in it.

It's always risky if you invest all your money on any one investment and Bitcoin is unpredictable there could either be a great price drop or a great hike so investing all your money is too risky

People are holding Bitcoin because as we all know there is a great hike in the price of btc which made there investment at great profits so they are waiting for more hike in price. So more profits

Cash is the basic medium of currency use. It's familiar to almost everyone and also acceptable at everywhere. Shopping in small nations btc is not that much accepted form of payment.
