i have found it a steep, steep learning curve but all you need is perseverance and accurate routine methods.
If its possible to create the new CAT with the save and reload properties for computer restarters out there, i would say charge 1btc as usual and free or 0.2 for previous CAT buyers.
I completely disagree to split or increase C.A.T. price. C.A.T. is already one of the premium priced bot working for crypto currencies.
More important is to improve the program, add exchanges.
Yes, to start with C.A.T. can be frustrating, but many have managed it. We have a help group on Telegram, where you get quick questions answered. I help on a daily basis people to get started via Team Viewer. Udemy courses are in the works, webinar programs follow. My Patreon site offers a manual, tips, headless server setup, and soon a template download service.
