I don't really have any issue with bitcoin itself but my least fav thing is the lack of real world places to spend it. I suppose the confirmations could be a little quicker but it's not really an issue to be honest.
The least favourite thing about bitcoin to me is that it takes to long time to get the first confirmation. We need to increase the block size.
Yeah that is true, but that is affordable when it comes to bitcoin, as bitcoin is offering us many other benefits so I will neglect the factor of delay in confirmation.
I am ok with delay in confirmation time but the other thing that I don't like is no one around me is aware about it and even I am not able to spend it directly in local stores around me.
i really hate that too, to be honest we surely need to make people know more about bitcoins around us because it is the only way to make companies start accepting bitcoin payments
i also dont like that it takes a lot of time for bitcoin transactions to be confirmed, it could be faster in my opinion though it is not a really terrible thing that wouldnt allow me use it
If we need faster confirmation the we need to increase our blocksize or else its not possible, and I think blocksize will increase if we have more users adapting bitcoins.
