I would place some bets for short distance events. As for long-distance ones, no one knows if Futuur will operate in two-three years. This is like having 50/50 odds about particular events minus some percentage of risk that the website will close:)
Yeah it's your choice since there are tons of options in the site to bet in , but i can risk for that long term of course with small amount that i can certainly lose 
futuur offers long distance predictions but short term would be safer .
and this is every gamblers prerogative so lets see what comes for long term of this company .
