Hello Gliss

I would like to suggest CENT coin:

Website (beta)
http://centcoin.org/

Exchange

Cryptsy
https://www.cryptsy.com/markets/view/97

Bter
https://bter.com/trade/cent_ltc

There is quite a lot demand and looks promising.

Have a nice day

look here:

Winklevoss twins predict $400b market cap for bitcoin.

so i guess one day it could reach $1000

NEXT Coin has great potential. i bought myself some nxt coins It has already a marketcap of $ 67,799,513.
