1: Even if you can treat it like an asset, it's an unproductive one.
2: It's too easy to have some sort of problem and lose it.
At the end of the day, I see the long term value of BTC going to zero.
I feel lucky to have had some at one point, just to have that experience. One day, I saw that Bitcoin sitting in my wallet, and realised I didn't really care anymore. It didn't solve any problems I was having, and I couldn't do anything with it other than look at the balance or send it somewhere.
I'd rather have my future wealth come from value I create, than some asset I happen to hold.
