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.
i guess it's depends on how the local exchange treat their user. mostly people don't have to wait till that long time, almost instant you sell your bitcoin for cash. or you might can make a deal face to face to those people who want to buy your bitcoin , it's faster.
