I have been using C.A.T. for a while now. It is a great way to make profit if you are an experienced trader. Even the most experienced trader should read the guide several times and start with a very small amount. As of the first weeks of July my top profit coins have been VRC, DRK, URO and VIA. I set it to get me the coins back instead of BTC. Last 2 weeks I have made over 3,000 VRC and 88 DRK. I setup URO for BTC and have made over 1.2 btc on that coins. Since URO dropped I am just collecting URO. Cloak, Crypt, MIN and Voot have been other coins I have been stock piling on.
I keep my min % at between 0.8 to 1 for most coins on the ones I don't need to watch as much or less volatile coins. The more volaile the coin the more you need to keep an eye on it. All in all its a must have tool for most traders and since I stopped mining this more than makes up for the lack of mining.
