This is definitely over priced, Im not sure what they are thinking. 1 btc for 2k ethereum = 1 eth at 50K sat. At the current buy rate we will see around 600 Million buys. To be conservative lets say 200 Million token buys. I also asked in irc if there was going to be a cap and the answer was no. So I have no clue how buying into ethereum now is better vs mining or buying later. Right now crypto is so volatile that 5 months is an eternity at this rate I don't see how it will hold its value. BlackCoin already has smart contracts and black halo with a cap of 69 Million coins Pos, current price 14k sat per coin/token. Im pretty sure projects will develop that will challenge ethereum making it tuff for the token values to sustain for a long period of time. If anyone has more updated info than me as to why the value will grow on the tokens than by all means, open to other views. As an investors this whole entire project is way to complicated for me to understand what Im investing in and what my return will be if any in comparison to other exciting projects like blackcoin or vericoin that also have block chains were people could build on top of
And that is why the ethereum-team so carefully have labeled people who pre-buy ethereum now as "purchasers" and *not* "investors". That may seem like a insignificant semantics-detail for most people, but it seems clear to me it's been deliberately chosen for a *very* specific reason, and that is to make sure no "investors" will be hurt by it's obvious endless inflation-ratio (price-drop).
One can use common logic sense:
What is ethereum? It's mainly a "fuel" for running decentralized applications.
What is required from any platform that wish to become long-term successful as a "application service"? Look at any service like cloud-services etc. In order to be long-term successful as a provider of space where applications can be run, the price of such service *needs* to become cheaper and cheaper over time.
If you want to stay within the "laws of physics" in this area, one should then conclude with that; *IF* this platform becomes successful, the price of the "fuel" (ethereum) *MUST* keep on dropping steady in price, or else the application-creators/runners will not be able to afford running their applications in a competitive manner.
Ethereum looks awesome technically speaking. But "investing" in ethereum as a means of earning money seems foolish, unless they want the "fuel" to become more and more expensive over time. Which is in such case, absurd. Look at what disasters increasing oil-prices have on this planet. It forces poverty to grow. Not a pretty sight. If they want this "fuel" (ethereum) to become more and more expensive over time, it will then *not* become successful. Not a single talented application-developer/runner would even consider trying to use a platform for their application if they knew the run-cost would always increase over time. Imagine web-hosting become ever more expensive. Not many web-sites, if any at all; would exist at this point if such price-increase were a fact.
So, using the "elimination method" on all these known factors, we can conclude it will be a bad idea to "invest" in this "fuel" on long-term. Because if this platform *wants* to become successful, the run-cost of the applications *must* decrease over time. If the run-cost does not decrease over time, it will force the application-developers/runners to stop using it, or look elsewhere to run it at a cheaper more affordable price-level.
Which in turn, leads us back to my original statement of "why" they chose to use the label "purchasers" instead of "investors". I'm pretty sure the ethereum-developers are *very well* aware of the exact details i just wrote in this reply, and chose their semantics wisely thereafter to avoid pitchforks and torches outside their houses at night sometime in future.
Now, all this been said; As a short-term speculative "investment" this may very well turn out to be *incredible* profitable, since it seems to have gotten unprecedented hype-factors for months. Or it may very well plummet like a rock as 80% of all super-hyped stock-IPO's usually do when launched. (And yes i'm using the IPO semantics here even tho ethereum itself does not. Just because someone does *not* use a definition, does not mean its not the right one to use. If it walks like a duck, if it quacks like a duck, its a goddam duck) SO, one should calculate risk Vs Reward factors before purchasing (and NOT "investing" as the ethereum-devs clearly points out in their demographics) this "fuel" at the very least.
TL;DR:
Ethereum looks like a awesome project technically speaking, but in order for it to be long-term successful the price of the "fuel" (ethereum) that is required to run the applications *must* decrease over time to stay competitive. Thus, a long-term "investment" in such "fuel" would then be foolish. It would then be better to buy this fuel *when* you actually need it. The ethereum-devs further strengthens this fact by intentionally using clear semantics in their documents that you are a "purchaser" of this fuel (ethereum), and *not* a investor of this "fuel" in their demographics on their web-pages.
Are the units of Ether not divisible like Bitcoin?...
