Every investor has taken a massive risk by putting their hard earned cash into MaidSafecoin. Even now, as the first green shoots of the network push up from the dirt there still a massive degree of uncertainty about what will happen when the very cool ideas being developed here meet the crazy variables the real world is sure to present.
I'd be surprised if anyone would have invested, with such long odds, without sharing the ideals of privacy, security and freedom which are inherent to the SAFE network. Without this bunch of mad and idealistic risk takers we'd be nowhere near where we are today: on the brink of a decentralised and private internet! If investors got huge returns on their original stake then awesome, they deserve it for helping to breathe life into this potentially very important project.
Anyhoo, back to the original question - what will Safecoin be worth at launch.... There is really no economic rule which one can really apply here, but I'll throw some interesting ideas/numbers which influenced my finger in the air prediction:
Number of Tor users: around 2 million a day
Number of bitcoin users: around 2 million-ish (prob a bit under that I reckon)
Number of Spideroak users: around 1 million
These are some low end numbers I think 'we' should be aiming at I think and totally achievable in pretty short order if this is what many of us think it might be.
For higher end numbers I'd be looking at the number of Facebook, whatsapp and instagram type numbers (in the hundreds of millions of users basically).
It's worth noting that Safecoin is very different to other crypto currencies. It's attached to a potential runaway madman (the network itself and all the apps). Your Safecoin will directly relate to a finite portion of storage and usability on the network, so in an odd way it's a bit like owning a certain % of shares of the network (as you would a company), not just an arbitrary % of available coins. At least that's how it works in my mind.
This iteration of the idea might have some fundamental floor none of us is wise enough to see from here. Or it just might not get the exposure/adoption it could for any number of reasons, but anyhoo (for a second time), and back to the the original question (for the second time too)...
I'm going for $0.06 by 25th December 2015 (not my 'launch' guess but better than nothing), and $0.71 by December 25th 2016, $2.23 (10,000%) by December 25th 2017
