Right now, in my country bitcoin and others crypto still unregulated for payment. We can not use bitcoin and others crypto for payment because its againts the rules, but i am believe in near future, government will regulate cryptocurrency because its getting more popular and many people having knowledge about crypto
I did not used it in my daily transactions, because it is not already accepted in malls in my country or either a fastfood. But it is continue to operate and hopefully soon i use it when time level up with bitcoin.
I do use it in many transactions that I made since I like to invest on some projects but it is not on the point that I use it daily since the transaction fees will really hurt you, it is really bad.
In the future, either the price is so high or expensive a lot of investors are so rich or there are a lot of transactions well also leading to a lot higher price of Bitcoin. They are useful if there will be a lot of platforms that will accept Bitcoin as a method of payment. Steam in the past accepted Bitcoin as method of payment but they immediately remove it because of the people that is abusing that method at that time and the way transactions fees are so high.
