"I'm thinking of either buying 1-2 extra R9 280x cards for mining, or the advanced trade bot instead, does anyone have any idea of what would give the highest ROI? "
Hard to say exactly. Haasbot licence is lifetime, the cards will be good for a few months and then you will need to sell them to get your ROI.
just visited haasbot's website, and it says you get the license for 2 years. Dont have this in my receipt when i bought this a few weeks ago, or any date mentioning when my license is over. Wondering how upgrades from simple to advanced are handled now?
The lifetime is indeed 2 years, it is written down in the terms and agreement. (this makes the cost for a single bot per year 0.075 BTC)
Upgrades are fully supported, if you have a Simple/Donation license then you get a full refund of that license if you want to upgrade. Of course on that moment the license time will be refreshed too.
BTW in general i should not worry to much how to expand the license, by that time (2 years later) there will be a good deal in place to extend the license.
BTW At the moment it looks like coming monday there will be an update again. The test results are still very positive.
