A place in Costa Rica or something that is a resort. The resort only takes bitcoin. As a guest, you have to use bitcoin. As the resort, we would have to train the guest on how to use bitcoin while they are in the resort. By the time they leave the guest will know how to use bitcoin and be comfortable with it.

This is actually a really interesting idea. A learning vacation. A mix of workshops, with beach, pool and buffets in between. 🏖️
Resort gives you a longer time window to teach, but any business can start doing this.
Who wants to open a laundry mat with me? Mining & lightning enabled
Ive had this same thought... perfect fit cuz the electricity infrastructure prolly somewhat alreadycin place. So ya im in 🙂
Ya just pull the heating element for each dryer so you can just have them spin. Then you pump heat from asics running 24/7 to each dryer as they turn on. Hydro’s for hot water washers.
So… being subsidized by the heat pumps, the energy saving can be passed on to laundry customers.
Free suds & tumble, while you buy snacks and learn about bitcoin.
