If you look at how few people there are who have bitcoin and how much of the bitcoin is owned by whales you will see that there is no way to make i stable. A single whale can break the whole economy if he want.

A few weeks ago, bitcoin is much stable i think and now the price is start growing.

Well, because people is comfortable to use a fiat than bitcoin, and still more people use it for investment than currency, although bitcoin can both.
And about the wales is exactly effected to the price.

It's not accepted by the masses because they're most easily manipulated ones. Masses read their media, and mainstream media only talk crap about Bitcoin usually, and they make news relating Bitcoin with Silkroad, busts, and other types of criminal activities... This isn't getting anyone interested in Bitcoin of course!

As I've said in other threads, price fluctuations isn't the worst keeping the masses away, fluctuations can be attenuated by services like BitPay...

Trust.
Trust is work, serious answer ... value is not Trust, it's the users that it build Trust.

I am just learning about Bitcoin and pale in comparison to many here on the boards, but here is what I am thinking on the question:

It is an interesting thought about stabilization of Bitcoin despite the fact it is a decentralized digital currency.  I think the misunderstanding by mainstream society is a great part of the instability as the powers that be are not favorable on it.  I do think with trusted and established fiat currency, there are ways to manipulate the system also causing chaos so "stability" is open to interpretation.  With Bitcoin there are stress tests for concern along with, as I understand it, unfair mining practices where it be almost too competitive for casual miners to achieve a gain.  There are still pros and cons with Bitcoin which I am still trying to get my head around. Because it is not backed by any sort of commodity such as gold, it makes transactional value converting it to traditional currency difficult.

Some states like California are making legislation incorporating rules on it, but it has a long way to go before it is truly accepted as an alternate form of payment. In the San Francisco Bay Area where I live, I can only think of one brick and mortar store that accepts it as payment (Nakamoto's). I wonder if it will take the economic decline/collapse of (multiple) countries like Greece and within Africa to gain momentum and enough following to instill a sense of stability and for that matter viability.

I could be way off base, but that's how I see it.

it may be gaining the trust of the GREEK masses!

Bitcoin is stable. Look at the fluctuations in value of the other popular currencies. Everything fluctuates, Bitcoin is no exception. The fluctuations in price are just a factor of the bigger system.

You would not like what the masses say about bitcoin. Bitcoin was mentioned on some website in the comments, and the poster was teared to shreds by "the masses" who all said it was a pyramid, ponzi, get rich quick and something like that.

It's the opposite.

The masses need the trust of BTC
