Nah man you're correct, a press release is something important and I wouldn't make one myself either. This has to be done by the person who knows Supercoin best, the Dev would be a wise choice since he'd be the one who can bring up the best points of Supercoin in 100 words. 100 is really short to bring up all good things about Supercoin.
I have 60 words and it could look more professional. Let's work on that
Supercoin is pleased to announce the release of “SuperSend Trustless”, the first real p2p decentralized trustless anonymous system, on August 25th. The team is very proud of the recent development and will begin testing the new system on MammothCoin and SuperCoin in the next few days. The system is now working end-to-end and Supercoin is very excited to move forward with this project.I would write something in the lines of
"the first in-depth explained p2p decentralized trustless anonymous system with published whitepaper" instead of what you wrote. At least I would write that because I'm not technically competent enough to say whether other coins (you know which one I mean but i'm not intending to FUD them) have a working one too, but if we release full whitepaper we'd be the first one to actually put something like this on the table (since others couldn't do this before us...).
If they appear to have a working one aswell, good for them. And i mean it ! Since our dev built one from scratch and ours is unique, it wouldn't give real issues for Super's future. But we'd be in the wrong then in our press release. And although I see that when our whitepaper is being posted on this other thread, it always gets deleted, and the fact that they aren't publishing theirs at all, it kind of says enough for me
though I'm just a more careful person i suppose.
