what problem do you have in bitcoin.
For me in my experience that I encountered in bitcoin was when I convert my bitcoin into a real money the confirmation took a couple of hours before it confirm to my email, I think its almost 8 hours before I claim my cash. Aside from that experience no more.
Really? I have never faced that problem as whenever I sell my coins and transfer the funds to my bank account it hardly takes 10 minutes from the trader to transfer the funds, btw I use localbitcoin for selling my coins.
