I think it will be better to make a similar bot for other exchanges as well. As you're good at programming and you can make those bots for the users of other exchanges in your free time. A lot of members on this forum aren't Kraken users and that's why it's better to make a similar bot for some other famous exchanges that people use. I would also recommend you to add daily and weekly interval option into the bot.
I earn absolutely nothing with this bot. I do that completely in my free time. And since I have no use for other exchanges and kraken is pretty well spread over the world, I don't see why I should put in that additional amount of work. It anyways would require creating a separate bot, since a lot of thing in there are specific to kraken.
You are free to do that yourself or find someone who does that for you, of course. My code is open source.
I wrote this bot for myself and was sure that there would be people thankful for it, so I spread it. If you are not amongst those, that's completely ok, but a lot of people seem to be happy that it exists. As long as this is not a paying job for me, I don't do work that doesn't improve it for myself. I did that for some currencies I don't use and people asked for, but supporting another exchange means hours of additional work.
