Educated a Financial Literacy Group about Bitcoin

How would you respond to these criticisms against BTC?

1. Bitcoin consumes a lot of energy and doesn't contribute to ESG Initiatives?
2. What would be BTC's future use?
3. Why and how would it replace fintech when its value is not stable and sometimes used for illegal transactions

Thanks for your help! Just needed your thoughts to convert them as a bitcoiner

I would say it is a successful post about the 3-year performance of my Bitcoin portfolio as I got a lot of interactions from this thread. Hoping that I orange-pilled most of its members
