In 2014 you could release a coin with a different theme and slightly changed block reward and an exchange could pick it up, then you could dump your premine, lather, rinse, repeat. Then you had to put in more work making your coin look legit, and continue developing it as an actual legit coin if the community/market took it favourably, or dump your instamine/premine if it didn't.
Now it's hard for devs to add any marginal value to the space without creating a coin that doesn't do something specifically different, which takes a LOT of work. It's that much harder to give a new coin any new value in the marketplace. So from a shitdev's perspective, it's easier to ninja launch a clonecoin with very little info that everyone thinks "might be the next Crave", attach a trojan to it, and attempt to get at the coins on users' wallets that DO have value.
In the case of vaporcoin, I think there was a coin called vapor launched at some point last year that was DOA but I can't find the ANN thread. There were a lot of post deletions by the dev-- FUD or not, a dev should be aware of the environment of distrust that exists right now due to Draculacoin and address rather than ignore. And with no working source on launch or attempt to prove wallets are clean (how hard is it to post a hash and virustotal link in your OP?!?) I think any of the U part of FUD, uncertainty, is justified.
Even though Yobit will add goddamn any coin before it hits block 300 it doesn't necessarily mean you instamined a sleeper hit that's gonna make you rich let alone break you even. In the current environment you should be very judicious about what you mine and what you pass on.
Absolutely my opinion, every single word.
And my 2cents: There was no algo and no bitbucket at launch. The wallet source downloaded from mega did not launch in my sandbox, I did not try the bitbucket source yet.
