It's you who need to be mobile not your fucking real estate!
And how much is that boat you posted? Several million dollars? You can instead have a handful of "modest" properties spread around the world for that much. *THAT* would be mobility.
No, really, how much is that boat? (not even considering fuel, maintenance, staff, etc...)
That boat is around $2 big*. It is nearly 20 meters long. Which is too big for many people I admit. Wouldn't be much of a trouble for a btc multimillionaire though.

You can get a bit smaller one (around 14-15meters) for a way cheaper price. Usually under $500k.

Fuel is only needed for emergency situations and when you are entering/leaving the port/marina. Maintenance costs would fuck you up though. So does marina rents. Consider these as a rent to live in a mobile house.
All in all a 15 meters long boat is pretty manageable according to my calculations. Pretty doable. I need to hoard more bitcoins.
