Don't worry. On the official site it says: "Signatum is designed to be easily integrated into several applications, including payment platforms, exchanges, and marketplaces." - and that's the tech behind SIGT, as I was answered here - "designed to be easily integrated". So it should be integrated easily. Not more than 2 weeks I guess, or a month maybe. Actually, the windows QT wallet is the same as most of other wallets I've seen so far - same interface, same RTC, etc, etc - they're all copycats.
And based on the level of questions people ask and answers in this thread - I see that there are 30% of bots, shouting "buy SIGT it's the future of donald trump would bought!", then 30% of Witnesses Of The SIGT sect who should "it's the future tech! can't you read? it says - easily integrated, yupi! no other coin has that!". 30% of investors who bought in and don't know how to exchange to BTC to withdraw their money from (not worth to mention) craptopia. And 5-10% of real users, who are sometimes questioning themselves - "what the hell am I doing in this circus?..."
So I'm not worrying anymore. It's a perfectly normal example of discussion here, as I understood.
They also list the estimated block time as two minutes in the announcement and white paper, but it has been averaging at 63 seconds for the last 80000 blocks. Just saying it doesn't make it true.
Still, it has a better return than nearly every lotto ticket I have ever bought and you never know this might be the one. That is worth 10 more days of mining and circus.
