Being a new miner myself, started in Dec 2016, I think the biggest challenge is patience. I originally bounced back and forth between Antpool and KanoPool before finally deciding to land here for the long term.
If you have zero patience, you will never be happy with the pool you are in. STAY WITH KANO, you won't regret it.
I also want to take this time to thank all of you who contribute regularly to the community. I really appreciate it! It has taught me a lot and I hope to someday pay it forward to others as they join.
