Bitcoin is the simplest as a payment method but for a small transaction the cost or fee is extremely expensive comparing to another payment system such a PayPal. I think this is the reason why people still don't want to use it, there are so many options for payment method right now, bitcoin also is not accepted widely due to the popularity or government regulation, people in other countries can't use bitcoin for payment/currency it's against the law, so far fiat still the best choice for everyone whether using PayPal, debit card, etc.
Surely this bitcoin is not yet fully usable as a payment method as it is a digital currency. But this day's bitcoin is already great when it comes to investment because of its market price when you invest in bitcoin for sure you could earn big money of money when you buy low and sell it on a high price. Also as a currency or using bitcoin for buying or as a payment method for sure in the future the bitcoin could easily be implemented if all of the transaction is already made online.
nice to see that some people are like me. we are on the same boat op because i also use my btc almost everyday . i use it directly without conversion to local currency , and i dont care if the value falls or goes up but im just happy using my btc . i been using btc for over 2 years now ever since i discover it . the challenge that we commonly face is the support for btc and its volatile nature but soon , idk if these challenges are going to be fix when more people enter the bitcoin world .
Agree, whatever bitcoin is we can already see that bitcoin is already a success and we earn in bitcoin we know that it is not yet ready but bitcoin technology already has what it takes.
