For me, probably the transaction confirmation times. That is one the biggest wow or attractive factors with bitcoin for myself personally. It is getting too long.
I also have that problem but one of my other problems is that it can sometimes can be a while before you make money with the Bitcoin again. I know that you will have to be patient with Bitcoin but I do still not like it.
I hope that I can make money fast again.
Same I want to make money fast again than now, but I'm tried another way like to gain bitcoin fast but it does not work because I'm not had a patience and i'm a careless person. until this i always tried another way to get more bitcoin but i never try suspicious ways. we have an same problem and maybe can find the answer to this problem.
