is its choice of ECDSA is known to be weak and have a back-door, while MONERO may be 'secure', its not secure from the ppl you should fear ( NSA wrote the ecdsa curves for monero )
Can you elaborate what you mean?
ECDSA is maybe 25 years old and the cryptographer who offered ECDSA solution passed away years back...
And from I have read I quote: "a large number of brains have studied the possibility of designing a quantum computer to attack the security of algorithms such as RSA or ECDSA. In the case of ECDSA on 256 bits however, it seems that the laws of thermodynamics do not make it possible, in the current state of knowledge"
