Very quickly, lets think this through.
If the dev were to dump it would be lower than b3 because Im sure they have far more than the entire marketcap of this coin right now, not to mention the buy orders have been thin for some time now.
As a dev, would you dump when your coin was listed on a tiny "micro-cap" exchange, or when your coin is actually worth a fuck because there are mass amounts of people who get a huge cryptoboner from the word "masternode"

Further, the PoW period had a ton of miners... where do you think those coins have been going? What about these insane masternode rewards? Just saying... if a dev is worth a fuck and has two brain cells that can wire together they would wait because cryptopia listing is around 5 btc, but youll easily spend .25 btc on a node if you bought it earlier today. Its a no brainer.
I love how everyone immediately assumes that its the dev who is burning the house down immediately.
