To give you that, the community is thriving. Certainly also because of the DeepPoints and so called airdrops, which they are not, but a form of payment for doing marketing. Well, up to you, I consider it way too spammy and counterproductive.
But what makes a coin is not only community but also technical innovation and practical applicability.
DeepOnion is a copy & paste coin from BitcoinPlus (TOR) and Peercoin (PoS) and a few others where they took code from. Other than that there is no and no own innovation in the code. Not even the holy grail called "DeepSend" which is their word for coin mixing could be implemented to date, and I doubt it can be done by Crypto-Rainbow. He is too busy with censoring forums rather than doing any dev work. Nice graphics and a forum is not what I call innovation.
Practical applicability, well, to keep it simple, I would at least count active trading on exchanges a key feature a coin needs. DeepOnion is barely traded as nobody is selling, a direct implication of their requirement to show the coins in the wallet for the next marketing payment aka "airdrop".
So, there is only one thing DeepOnion has, an active community of members who do the groundwork for a handful of anonymous people in the background to drive up the price, so they can dump their millions of premined coins in the end. Good luck with that.
Taking parts from different coins and combining them is nothing new and DO is not the first to do this. There are alot of projects in the top 20 that have taken pieces from other projects. QTUM has parts of ETH/BTC, Monero is from Bytecoin etc. Almost all POS coins have taken from Peercoin b/c it was the first.
Deepsend will be modified from Supersend which is a feature from supercoin i believe. There are a ton of projects which have good features but feel short on the marketing and never took off. DO is using the available portions of the tech that they believe is out there to build their project. Everything is open source, so why start from scratch?
This type of stuff happens in the real world everyday. There are tons of product types that don't take off until someone comes along and modifies and markets it right.
