I don't have anything to complaint about bitcoin but I don't like the fact that there is nearly no shops in my place that really accept bitcoin. I did see a coffee shop that has a bitcoin signal but it seems to be that it doesn't really mean that it uses bitcoin.
I think that is not a big deal as we can use them by converting to fiat and in future even this issue will be resolved and we would find many place to use them directly for buying things.
I think people will be happy to shop using bitcoin directly, in addition we will be happy and proud of course use bitcoin transaction will be instant and fast. of course it is a problem
Everyone is looking and willing to spend their bitcoins directly but most of the countries are lacking the development of bitcoin and it cannot be used everywhere for buying anything.
