Yet again, instead of replying to us, you post another "formula" that is now free of charge ?
Are you still trying to sell your original one ?
Are you completely ignoring our concerns here ?
Please go ahead and answer everyone in this thread one by one before you continue to advertise

Dear Sam
I've sold the original model to someone in a high price so that I can't sell it at a lower price because that's not fair to previous buyer. What I'm selling now is model002 and I took all your advice to low the price to $100. The free model001 is provided to check if my formula work or not. Model001 is original for sale but now I offer it as a vouch copy because I took all your advice. I know all members here are best of best in BTC trading field so if any advice is concerned about model please be kind to tell me. I'm a newbie here so I apologize if I didn't follow the rules here.
