New coin is released, you want all hashing power you can get to mine in first days, looking at profit if it makes it to any exchange, would be one of my guesses.
That is correct.. Lets take an example from 42 which I mined only for few hours solo i had 24000 dents which i sold for around .45 BTC
you are always taking a risk when mining new coins. RPC/CAT paid of initially but on the other hand GFT,MOON,COYE,HOLYNOODLE etc failed but
soo... its a risk
