You can also look at it this way: rather invest in a coin/dev that come up with the new idea, rather than one of the dozens of coins that copy the idea.
You didn't come up with the Multi Pow idea though, well not according to the digibyte announcement page. I don't see myraid coin mentioned once so as a new user I will just assume it was the digibyte devs who invented Multi Pow.
Security: 5 DigiByte mining algorithms vs. 1 Bitcoin algorithm.
DigiByte mining is much more decentralized.
DigiByte mining algorithms can be changed out in the future to prevent centralization.
September 1st, 2014: MultiAlgo hardfork at block 145,000. DigiByte plans & successfully deploys its second hardfork to allow miners to mine on five independent mining algorithms & is the
first digital currency to make such a move.
Interesting... I guess they mean 1st to copy Myriad?
Actually, IIRC, wasn't it Safroncoin that was the 1st to copy Myriad?
Edit: I think I see what they mean, the first existing single POW chain to move to multi POW... That's how I take it I guess...
