I still have a copy of what crazy hosting plan offers.
You can see what happy hosting plan offers at DH
Probably this will give you some ideas.
I believe per cycle means per month at DH. It means you have 8.89TB BW (Bandwidth) per month. Used this Cycle indicates how much BW you have used.
No except unlimited disk space and unlimited bandwidth with happy hosting plan.
If you are happy with your current disk space and bandwidth, you can stay and save $1/month.
A busy site will not survive on a shared server. Depends on your traffic, you can try DH VPS first then dedicated server.
