if you have a bitcoin you will not used as a money
I totally agree... also Bitcoin is unusable as a form of payment when it sees mass adoption which is the biggest problem of all.
this is just your perspective not the reality.
you can check the payment processors to see a small part of the total amount of payments that are happening through bitcoin. they are processing millions of dollars worth of transaction. and that is only one payment processor (bitpay) there are more and also there are a lot of merchants that are accepting bitcoin directly without any processor.
