From the look at the price it's at the cheapest price it's ever been, even cheaper than it was at the Protoshares stage. Anyone buying now would be buying in at the early adopter prices.
And eventually the price is going to go way up again, just as it did with Bitcoin, Litecoin and any of the others. As long as the developers continue to add utility, improve UX, improve the UI, these low prices will not be sustainable.
At the same time Ethers are cheap also, but at $1 people might not get as much ROI as they could get in BTS. This makes BTS as underpriced as it is, a very good buy at this time. At the same time if anyone can earn it, it would be very wise to hold onto it.
I did some math, and Ethereum could someday be $50 or $100 each if the market cap gets high enough and it probably will. Bitshares on the other hand could someday reach 50cents to $1 each, with a reasonably high market cap. This would mean you could acquire potentially $200,000 worth of Bitshares for the price of 1 Bitcoin?
You would think every Bitcoin holder who has more than a few Bitcoins would put at least 1 BTC into Bitshares, but it is likely the Bitcoin distribution is extremely centralized, and this would explain why we don't see that. On the other hand with a fiat onramp you might not need BTC to acquire BTS and if people are willing to earn BTS you also don't need BTC to acquire BTS.
The rise of Ethereum, SAFE Network, NXT and others will also have interesting implications for BTS. Altcoin holders might be more likely to diversify, and individuals who feel that Bitcoin is too expensive might be more likely to diversify as they have in the past.
A prediction I'll make is that December-Janurary will be the best months to acquire large stakes in BTS. Save your money for those months.
