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.
He doesn't say anything about trading time for money. If he creates value that scales, he can divorce his time from the money he makes.
There is no dilemma here.
I do agree that bitcoin (well, blockchain in general) has useful properties for certain types of transactions or record keeping.
But I think the points of the article stand. If a currency isn't useful to buy things, or is subject to wild value swings due to speculation, then it isn't a great currency. If an asset doesn't have any real value to any customers, then it's not a great asset. Bitcoin combines both of those into, a mediocre currency and a speculative asset?
The people buying bitcoin as an investment don't need to care about the asset or secure network, in fact bitcoin's technical details have actually created negatives when exchanges/vaults/services break and assets are lost.
To most buyers it's just like buying and selling stocks, currency, gold, oil futures, whatever.
