Yes. I have noticed that. But the price is entirely driven by the many available SIGNUM use cases like cross-chain trading and games like cryptoball. There is no "hype". If someone like Elon Musk were to discover SIGNUM, it would get noticed by the masses. And the impressive (working!) ecosystem will stand up to scrutiny.
There may be a time, a few years from now, when everyone kicks themselves for not buying SIGNA when it was less than 0.01 USD.
