Yes, BTC is the most wasteful. Other things we think are wasteful, are not - either they are for pleasure, or they are byproducts of other things, or they are contextually relevant (i.e. weapons/war), part of the systematic inconsistency but not strictly wasteful. Even then, there are benefits. Mining BTC using electricity is up there with the stupidest things we do - there are many ways to distribute new BTCs, handing them over to those who consume the most resources is a terrible idea. Given the cost of electricity and that it's a scarce resource, often subsidized etc. - BTC mining should probably be illegal unless you make your own electricity. My local government is actively trying to court BTC miners, with what is subsidized electricity - I can't think of a more directly wasteful thing to do.
