Can I just buy Wings and keep it for like 1-2 years as investment? or Do I have to forecast something otherwise I will lose the coins???
You can keep it as an investment. You don't have to forecast if you don't want to.
Good to know, thanks! But what is forecasting, is it like gambling? I can lose coins if forecast is wrong??
No, you don't lose your wings if you forecast wrong, the closer you are to forecasting correctly and the more wings you back up your forecast with the more rewards you get from the distribution.
