Giving olympian gold winners altcoins is meaningless, don't you think? These are gold medal winners, who are going to get rewarded by their governments and probably make a lot of money off of sponsorships as well. I'm fairly sure they won't be interested in any "airdrops".
I think right now they value Gold as physical asset and the want it valuable, they appreciate bitcoin and alts but right now it can't be rewarded by government, Probably in few years to come they will use it.
