Graph below shows hourly traffic with Hostgator
Namecheap - I transferred my site to namecheap and registered with shared hosting. The traffic even become higher. After 2 days I contacted namecheap support. I told the guy to tell me if my site is causing trouble to their shared server as I see a 100% CPU usage inside my Cpanel, the guy said "not at all" and I don't need to worry. He also told me that my site can be down in just "seconds" but it is automatic and will be back right away if the load is really high, and if in case there is a possible problem they will contact me through email.
It's 3rd day now and the traffic is still around 4K per hour and the site is still fast.

My site could have been long dead if I stayed with hostgator and also lost a lot of $$$.
I hope namecheap stays forever with excellent support.... I spent $106 in long distance call to Hostgator support
