Trading and investment is also speculation, because Bitcoin is a speculative asset. The difference is only in time preferences.
I disagree to say Investment is Speculation. At a tip of meaning, investment, trading, speculation look to be similar because people do it with purpose to get profit but if we look deeper, under the tip, they are different.
It's still speculation by definition:
investment in stocks, property, etc. in the hope of gain but with the risk of loss.
Just because you think there is no risk that there's something fundamentally different between Bitcoin and other investments it doesn't change what it is, you buy now in the hope of selling at a higher price!
With Trading and Speculation, they focus more on short term profit and don't care too much about value creation of what they spend money in.
And you think investors in Bitcoin care about what value they create? Common!
Besides, there is no money "in", the money you invest doesn't go in Bitcoin, it goes into the pocket of the guy who sold you the coins, that's why the zero-sum theory, because you can pay 70k for a coin, but if nobody else is willing to pay more than 7 cents, that's the value of it, the 70k "invested" are long gone!
