Lets see, current rate is 2000 satoshi each. 10x would be 20k satoshi each or 0.0002 each. That would put it in a marketcap of 3.5 million. It would rank 17th, just behind quark, vertcoin and XC. This doesn't seem unreasonable. But lets be conservative and say 5x, that would put us at $1.75 million. That would put us at 24th place, just behind Maxcoin, Megacoin and InfiniteCoin. I see Silkcoin to be more innovtive than these coins and a 5x increase seems very resonable. A 10x increase would completely depend on the eco-system and its real world utility which is still a complete unknown.
I am optimistic ofcourse that if the dev's follow through with their roadmap then we are going up in terms of bitcoin by multiples, the amount of multiples is anyones guess.
Now, we would go straight to the top 10 if the devs implement the marketplace which allows the free selling of anything. This alone would create a lot of buzz and media attention. People using blackmarkets in TOR would flock to the silkcoin marketplace. Actually I would love if their would be a community driven voting system where certain types of goods could be voted to be taken off the market. In other words the community decides what is allowed or not allowed to be sold on the marketplace. This would remove the developers responsibility to flag certain goods and put it into the communities hands.
Also think of the implications of just selling everyday goods on the marketplace instead of ebay, no more 10% fees per item and little to no more listing restrictions. A marketplace owned by all of us.
The OpenBazzar project (AKA darkmarket) has seen a lot of media attention and buzz already just imagine if the eco-system beats them too it, silkcoin would become a household name.
So when you say 10x is highly unlikely it should be rephrased to a "complete unknown", as you are just judging from your previous trade experiences. The reality is the market does not know or has decided what the value of silkcoin will be with these never before seen innovations.
(Note: I am a fan of Terrence Mckenna and a lot of his philosophy on certain mind altering substances, It is not as simple as "drugs are bad Mmmmkayyy", i'll just leave it at that)
https://www.youtube.com/results?search_query=Terrence+MckennaThe "silkcoin marketplace" <-- doesn't that look and sound perfect? If more developers get envolved to work exclusively on the eco-system/marketplace it could rival the bazaar or integrate the bazaar into the wallet. No one knows what will work best, but this could end up inspiring new projects or becoming a huge project in itself. A 3.5mil market cap will change everything and this will start looking like BC development with that level of investment money flowing in. -Wont you be glad you held your coins then?
