So where are the Devs lying ? can you provide quotes / source.
Pretty much every time they say this:
What we can do however is to make sure the roadmap is achieved and Signatum gets real life usage. We will continue and try to innovate and update.
There is no innovation in this coin whatsoever. It is a clonecoin, pure and simple.
That is, and has been, the lie from the very beginning. Fuelled by a plethora of sock-puppet forum accounts frequently posting fanbois cheerleading or false news of 'inside info' that big players in the cryptocurrency industry are interested in this coin, when there is absolutely nothing for them to be interested in at all.
They haven't taken the Blackcoin code and improved on it, they've taken the Blackcoin code and simply chosen a few different attributes regarding which PoW algo to use and things like the coin supply, blocktime, reward etc and then renamed it 'Signatum'. The exact same routine all the clonecoins are created by.
Forgetting to change the leading 'B' in the address format, though, that was truly sloppy.
EVERY coin after BTC is a "clone coin" or a "clone coin" of a "clone coin" ad infinitum. I haven't looked, but I'd bet every single coin around shares 90-95% of BTC's original code. That doesn't make them a scam. Seriously, enough already. Almost everybody that's ever likely to read this forum has already seen your very subjective, and at times naive, analysis many times over. Why do you insist on trying to cram your opinion down everyone's throats by spamming it over and over again?
