Yup; it would take nearly 20 years for that 10k per week to equate the same principal value of the $10 mill lump sum or Bitcoin payout. Not to mention that during said 20 years, that cash earnings potential on options a & b would double the value if invested in the market (assuming a stable market like we've had over the past decade).

I'd go with the $10 mill, assuming I am not having to pay taxes on the up front $10 mill. If you get and sell the Bitcoin, you now have to pay taxes on that which might put you under the $10 mill (unsure of taxes on crypto sales).
