Uhm, I'd say it's not entirely a bad idea going into rental businesses outside crypto space. Don't know shit about Airbnb tho, but being one seeking some more diversity in my investments, I mean, recently this was one of the reasons I hopped into taxi rentals. So basically you purchase one or two, or just whatever number you want, get a driver/s, do some paperworks and it hits the road. You get your daily/weekly pay while he/she rides the day out.

It's a pretty nice investment, but as usual, comes with a lot of aches like repairs of the casualties, tho this only applies to vehicles not on higher purchase...
