Just had a look at
https://payticoins.com/ and the website doesn't even have a logo on the tab, any reputable website would have a logo on the tab, but PaytiCoins doesn't, the first sign of something, have a look here:

Then just take a look at the affiliates tab on the navigation bar of the website and it says that your affiliate cut is 10 percent. 10 percent. Let that sink in. How can any site make any profit when it is giving 10 percent to the affiliates, either the site is offering you say 80% of what your Bitcoin is really worth, or the site is a scam. And looking at the website's design, I would say it is leaning towards the scam part.
The first site is definitely a scam, will be back to review site 2.
