Just switched from ZEC to SIGT with my 17 x GTX 1070s yesterday.  Wow the volatility of this coin on Cryptopia is something else!  And I thought ETH, ZEC, etc was volatile.  Nothing compared to this coin.

I've read the whitepaper and checked out the website for SIGT.  I must say I'm impressed with the concept of a short mining period and future/planned developments.  Not sure how the coin price will play out in the short term, but the sky should be the limit if the dev can deliver on what he's promising regarding real-world applications.
