looks like nothing but a copy of monero , i dont understand how and why this coin was worth a dollar few weeks back

now theres a tough competition between the anonymous payment coins with many coins having new innovations ,simple copy coins wont succeed
So why Litecoin now is worth more (far more) than $1?
Also, you clearly didn't read Masari roadmap. Take a look at it in the official page, and check some new things they pretend to implement that will truly differentiate it from Monero (and can also even serve as an practical example for future Monero implementations).
