It's really the last day of superprofits.
It's gonna be the last day of any possible profit for this one. Because of block 10k and block reward gets halved. when you can't mine the coin enough for it to be profitable, you dump all you got. Then the price plummeth to abrahamistic hell and never goes back. We got lots of dead altcoins out there, they all follow the route
Several flaws in this logic I think.
First, as user abant pointed out, the block reward is halving at 30k blocks, not 10k. Long ways to go until 30k blocks.
Second, it makes no sense to argue that all miners will pull out and dump right at 30k blocks. Many miners have been selling as they go. Why would all miners hold 100% of their mining income until block 30k, then suddenly decide to sell it all at the same time? That would be a stupid way to approach mining, and most of the mining is in the hands of people doing this for a living.
In general, people arguing this is a pump and dump are not pointing to anything bad about the coin (e.g. untrustworthy developer, large pre-mine, nothing innovative, or some other bad factor). Quite the opposite: the coin actually has a new algorithm, which alone won't keep it alive, but certainly makes it a large cut above other junk coins based on scrypt, x11, etc. User doktor83 also points out that transactions are fast.
EDIT: I want to add that SIGT also has community support in the form of MORE than just empty posts saying "we like this coin". User crowetic spent 0.97 BTC to get it listed on Cryptopia. That's a powerful community voice putting its money where its mouth is: real support.
I think there is clearly some uncertainty around what the exact value of this coin is going to be. There is no clear roadmap. But uncertain value is not the same thing as it being a pump and dump. People are investing right now in the hopes that either (1) the algorithm will ultimately gain mass adoption, which would be huge, or (2) the roadmap will reveal innovative implementations for this coin/algorithm combo. I think that makes it easily worth holding and mining in the meantime, because as long as you think there is at least a 20% chance that it will go 5-7x in true (non-speculative) value within the next year, there's no good reason not to buy in.
