Need Career Advice: Unpaid Blockchain Internship vs. MNC Offer

Hi everyone, I need some advice on a career crossroads.

I have two offers:

1. Blockchain Startup :

   • 6-month unpaid internship (accommodation provided).

   • Followed by a 2-year bond.

   • PPO: Max 30k/month.

2. Capgemini (MNC):

   • 4.25 LPA for Software Engineer role

   • No bond.

My Dilemma:
My heart is pulled towards the blockchain opportunity. It's the future, and getting my hands dirty early is incredibly appealing. However, my pragmatic side is worried about the 6 months without a stipend and the very low starting salary during the bond, especially when compared to the Capgemini offer.

Has anyone been in a similar situation? What would you choose and why?
