Isn’t it the case with DeepOnion that users have to hold something like 80% of their coins for a certain period of time? That makes me a bit wary - it feels as if the market is being kept artificially high.
My money is with XSPEC for now.
I believe what you refer to is the 90% holding rule if you want to participate in the airdrops. This rule does not exist anymore, see "All airdrop coins are yours and you decide what to do with them. There will be no 90% holding rule any more." on
