A big dump at the end of the airdrop is very likely, but this Project is very good, past the initial storm it will get its value recognized.
It will only show who the true supporters of the project at the end are. I'm sure the dev team will have multiple reasons for people NOT to dump at finale of the airdrops anyhow. And for those that do dump it will give traders that are not a part of the airdrops a chance to buy in also which will hopefully increase trading volumes.
I only have 3 onions so far but i am slowly increasing them through faucets and competitions but whatever i have after the airdrops finish i won't be selling i will be holding and watching the progress of DO as it continues to grow and push the boundaries skyhigh!
