...Now I like to transfer my QCN from poloniex to my pc. But the problem is I cannot my wallet address copypaste and their is some issue with poloniex where I cannot fill in my personal address.
I bought QCN at Poloniex and was able to transfer the coins to my wallet. I keep information, such as my wallet address, in text files and probably just copied and pasted the address from my text editor. The cryptonote wallet addresses are very long, much longer than bitcoin addresses. Here is my address that worked on Poloniex: 1PBL7vfv3oEBgVuE5yt3ptHydTACwuD6G9YVNpGLBgSYKN5wZbf1MA3CxfEU6aYNnDbktwyKCfJ2DM3

It's possible that the address had gotten truncated in the process of copying and pasting. Make sure that the address you paste is actually that long after being pasted.
The only thing I am thinking of now is; how on earth will it be possible that the every human being is going to use digital currency when the whole crypto-thing is so complicated. I know I am a noob in computerscience( but still attented university in mathematics and economics ), but a lot more people in world know far less then me about computers...
I agree that especially cryptonote coins are too difficult for ordinary folks who are afraid of the command line. Being a new technology, cryptonote isn't fully developed yet and as you see GUI wallets are now just being developed. Computers were difficult to use also when they first came out, but now most people are able to use them. It's takes time to develop technology and make it easy to use. Some people think that everyone will use cryptocoins in the future and it will replace all paper money. I don't believe that. Cryptocoins are more convenient to use for certain things, but other forms of money will continue to be used.
