Taxable Asset
Intangible Personal Property: Definition, Types, and Example
Anyway, I also prefer cryptocurrency because of the sole reason of having a low entry point, and higher chance of gaining profit due to its current status of being in early stages. Aside from that due to the same reason @coolcoinz stated, holding it is not taxable until we sell it at the higher price. While real estate is subject to annual tax even, reason why some think of it as a liability than asset when left idle for years.
Yes, I am Not joking here as according to my local tax laws I'm supposed to pay when I turn my coins into fiat money, so I hold for as long as I can and trade OTC as much as I can. Fortunately, barter transactions are impossible to track, so you can sell bitcoin for cash all you want and exchange it to goods and services as long as the other party is ready to accept BTC as payment.
I'm also a guy who likes to have things under control. When I own a piece of land I have to be aware of every single thing and fight for it every single day. I'll give you an example. I have a property near the woods. One day it got hit by a lightning and it damaged lights on the gate and the intercom. I had to replace that. The other day, a tree fell on the fence, I had to go there, cut it down, fix the fence. And this is a property that nobody lives on and I still have to pay taxes and pay for natural damages. I don't have similar problems with my bitcoin.
