You are just being practical. I applaud you for being so honest. Because the US fiat value is fixed and stable. The value of the fiat you were holding is the same value you can use to buy anything. As to what i've learned here, bitcoin is not a currency and will never will be because of it's volatility.

Govt will try to shut btc as its a scam according to them plus their tax incomes will reduce. This arises controversy of acceptance of btcs over cash

Real cash helps you in estimating your earning by solid calculations but there is no calculations in this virtual system

Because Bitcoin can only buy and sell on the internet, it may be necessary all the time, but there are very few people who can go out and do some shopping with Bitcoin, so I need paper money so my idea is soon that all sellers will buy Bitcoin wallet and start to trade with Bitcoin as if approaching.

Everyone has a choice. Yes, paper money can be used more conveniently in daily life. Paper money is widely used. But I think bitcoin is an investment, and you may be adding value when you hold it, which can bring you benefits.

I would not prefer paper money to bitcoins at the moment, because right now there is a rapid growth and there is simply no reason to compare and think where it is better to store money.

Well that's your choice. It is just a matter of perspective. Other people are using Bitcoin because it is not only a currency but also a good asset or investment for being profitable due to thecontinuous increase on its value for a long run. That's the biggest advantage of Bitcoin compared to fiat that are having a stable market price. The only issue on cryptos right now is the legalization and hoping that in the future it will be solved.

If you are earning a huge amount of bitcoins on cashing out then why bother to reduce a small amount of fiat on your transaction fee. Cryptocurrency payment method will be only efficient on paying a huge amount of bills if the transaction fee is really bothering you.

this is a question or a logical delivery, sometimes if I have to bother to bring cash when buying electronics, while in the street I think "it will be easier if I have money crypto and can be used as a payment medium in some places that I will visit ". like your story, when I want to buy a snack that cost me less how much I prefer and like paper money

We are used on using paper money so it will be more convenient and less confusing for us. Bitcoin may offer more than what paper money can offer. However, it still have disadvantages that may affect our transactions. For me, since it is used only with the presence of internet then, it will our transactions. Some may not still embrace this kind of change and still prefer the use of paper money. Lots of circumstances may occur. Like when the internet is not available, bitcoin will not be accessible. So I still prefer the safer means which is the use of paper money.
