Well I was going to say 42coin -- as it was starting another pump up cycle -- but it looks like that is already happening. It went from 4 to 5 in a matter of days. I hope everyone got to take advantage of this again
If you mine 42, stick with hash-to-coin pool -- they are the largest for 42coin and get the least # of orphans.
Other solid coins are BTB, NET, NOTE, FRK, etc.
