The problem which i face many time and may be also other users is taking a long time of transaction confirmation. its really made me upset and doubtful about future of bitcoin.
Yes indeed correct transaction issue is very disturbing and uncomfortable. I have experienced it when I really need. But it has often happened and I hope it can be overcome in the future.
For me it is not really a problem at all when we I'm having delay transactions or having hard time with it.
I don't mind it, I just letting it to happen.
And it only take a couple of minutes once a transaction is going to be confirmed.
