You need to prevent dumps then as a dev!!!!

Take an example at Unattainium. New coin, but damm it's bulletproof man.
You can't just 'hop in', and mine some coins, you can't mine it at instant high hashrates, you can't dump it quickly because of the network time.
Rock solid future coin. Would not be surprised it this hits exchanges at above 1BTC/Unat. Best thing i've seen in this Alcoins topic for months now.

Dev's need to learn from all those coins who get mined and dumped. But it seems they preffer the quick money over long term. Simple as that.
