I bought land with Bitcoin in 2018 and it has lost 70% of its value in BTC denominated terms since.

Not a single regret in the world because that specific piece of land will NEVER be available again, and I have made a ton of countless memories + grown as a human because of the learning experiences building it up.

I knew the odds of it losing BTC value going in, and was more than happy to accept it.

If you don't feel this way immediately, then either don't buy it or get a mortgage for it instead.
