Holding bitcoins is not investing, if bitcoin is money. Then it is just saving money. If it is a commodity, it is also investing.
Speculation is a derogatory name for investing. Some people regard short time, high risk investments as less virtuous than value investing. I don't. If you invest short time, high risk, you can even out the risk by investing in many companies. That is what the venture (= risk) funds do.
Buying something for the long term because you feel the market undervalues it is investing
Not if you buy money.
Buying something because you think you'll be able to sell it someone else for more, irrespective of underlying value, is speculating.
Only if you buy capital.
I am an investor.
Sure.
You think this because they money you have known in your life (fiat) is worthless. If you would have grown up with gold as the main form of money you would be talking differently. Bitcoin is just the same, it's as much a commodity as it is a form of money.
Furthermore, my above statements hold true for FX trading also. There is no way to buy fiat cheaper than it's actual value (a big fat zero) so everyone doing FX trading is speculating.
Sorry, edited my post. Well, we are disagreeing.
I try again:
Saving (derogative term: hoarding) is acquiring things or money for later use. You can sell them, without adding value (see below). You can for example buy food and hold in prospect of a catastrophe. You can trade it for something that someone else has saved. They can gain or loose value, doesn't matter. You can't add value to money, but they can appreciate in the market.
Investing is buying capital goods with the intent of making something of added value. Food can also be an investment, if you add value by repackaging, distributing or serving it.
Speculation is a derogative word for investing, meaning short time high risk, seen as non virtuous.
Looking at it again, saving can also be speculative if you take the risk that the stuff you save (money or things) will gain value in the market without the saver adding anything to it. So we partly agree.
