Contract Banking BA position at Wells Fargo.

Hello folks! I have around 6 years of experience as a BA. I have my masters from UK and my experience is mostly based out in Canada. I recently received a contract BA position at Wells Fargo from a consulting firm called «  Insight Global », initially I took it up for interview experience. I had couple of interviews with Wells Fargo team manager and I received the offer. The offer is 70$/hour with no other benefits, bonus or stock options. The contract is for 6 months with an extension up to 2 years. Is this worth it? I know BA’s are paid lesser than this and IMO it’s a competitive pay. Any insight on working as a contract employee for Wells Fargo. I always worked full- time before, so a bit apprehensive. I currently live in the Bay Area and this position is based out in San Francisco.
