And why did you choose this coin for mining - Masari? This is not the most famous coin on this algorithm and it does not have many exchanges. What is its advantage?
This is not fixed. Later, the coin will be changed more frequently. As a rule we select the most profitable coin based on cryptonight algorithm.
Currently Masari is more suitable for cell phones, because it has CN-FAST variant. Even old phones can have increased hash rate compared to Monero. Other coins with CN-FAST variant are not so profitable.
For rigs, please use other ports with bigger difficulties, e.g. port 1119.
