BitBay is Cryptocurrency market and in this week they will add XIN and other cryptocurrencies. Here is link to Bitbay

In my opinion is good to buy XIN before it will be available on Bitbay. For now Xin Price is about 0,024$ so it's very low. After XIN be available on Bitbay it should go up till about 0,5$ per one XIN or maybe more. I will hold my XIN longer.
XIN is limited and only 9bln available. For exmaple ripple is 100bln available and price is for now 0,25$. If XIN will have same capitalization than price will go up till about 3$!! I hope it will be so high :))
I will write something more about XIN, for now I am waiting with my XIN till it will be available on BitBay :)
