Also wondering if the OP kept his 400 coins? He would be happy now. Deep Onion has out performed all the other cheaper coins I've bought. Xspec looks to be catching up rather fast though! 2018 will be an exciting year for privacy coins!
In lieu of actually knowing what this individual did, I'll say "Of course he kept his 400 Onions!!!" You would be insane to let your pile diminish in the slightest until the airdrop ends...
