I have no intention to join any trading group if its not free, and joining that means depending on them for your trading actions and that is not a good idea.

Trading group is fine as long as you guys shares your speculation about the market, but if it became a pump and dump group better to leave early as possible. That money is huge already and you can use it to learn trading on your own, so don't join and invest on yourself first than anything else, learn to trade on the right process.
