Early retirement with crypto: what's your plan?

I've come across a movement called FIRE: Financial Independence, Retire Early. The main idea is to save heavily on daily expenses so that you can invest as much money as possible in the market with the goal of retiring very earlier than usual. I have a job that I don't hate, but my goal is to achieve financial freedom and have the possibility to decide not to work. I think that there are so many experiences that I would miss out on if I retired at age 70 as is the prospect in my country with the current laws.

People who follow the FIRE process usually consider ETFs the investment with the best risk-return ratio. As we all know, crypto can lead you to incredible gains or big losses and the average FIRE follower would probably consider it too risky for the purpose of achieving financial freedom (at least that's what I saw in many subs about this theme).

I was wondering what you think about early retirement and what role crypto could play in it.

I see DCAing into BTC and ETH as a way to speed up the retirement process by some years compared to traditional investments, but there may be better plans with comparable risk levels.
