yeah definitely take caution you may lose a ton of ONE's. It currently cost 9.11553 ONE for a single viper which is pretty nutty.

if you throw a stack of ONE at it, it will be obliterated and you will rely on the rewards to try to build back up your ONE count. I think this was worth it for early adopters who got 17,000% apr, and ratio back then was more reasonable like 2 ONE per viper. reward will be halved coming monday then again 2 weeks after.... so I'm not sure if you will be able to recoup your ONE count. It's mainly good for someone that really wants to trade ONE For viper. For me I looked into it as a possible means to increase my ONE count but I think using for that purpose has long since passed.
