There are many competitors for Monero, but none is powerful enough. And I will not discuss about the coins whose anonymity is not 100% certain, those I don't care about.
Actually the only worthy new competitor for Monero would be Grin, if people would accept its inflationary nature.
But you are bringin up Grim and Beam who have privacy flaws which do not make them powerful enough yet neither to truly be 100% private? Take a look below.
https://bitcoinmagazine.com/articles/battle-privacycoins-what-we-know-about-grin-and-beams-mimblewimble/ It seems like you don't even know if there was a bunch of competitors to the monero. when the anonymity platform becomes the trend last year there was plenty new anonimity platform like zcoin, and anyther anonymous platform. It will never take a new competitor for monero consider we still pegged to the centralized exchange site.
Haha of course I have read dozens of whitepapers through and through on pivacy coins but like NeuroticFish said none are powerful enough to bother bringing up.
I mean you guys aren't even providing a productive conversation, Scroda brings some fresh views in like not depending upon third parties when routing transactions and a unique mixing method only used to merge funds together in order to maintain unlinkablity.
You guys are so quick to bring up other coins who are not 100% private still instead of trying to take in information from a project that actually might have a solution.
