Advantages I think are it's anonymous and can be transported on your phone wallet and disadvantages are that it's volatile and can cost you money overnight.

Benefits: low transaction fees, money is yours (not in a bank)
Cons: currently unstable price, time it takes for confirmations.

You are right. Even gold has unstable prices, we do not bother that for investing into it. Sam kind of mentality would come to bitcoiner's mind set when bitcoin is more popular. Ignoring the price fluctuation of bitcoin will help bitcoin to grow rapidly.

In my opinion, the advantage of bitcoin is the value of bitcoin . 1Btc can be 300 or 400 $ (not definite) and the disadvantage, what a difficult to get 1 btc but don't tired to endeavor

Here is what I could gather from my own thoughs and other comments in this topic :
In blue: what is inherent to bitcoin.
In green: what has to do with the present situation and can (will) change in the future.

Pros:
- decentralization allows people to free themselves from the traditional banking system as well as governments.
- price fluctuation makes traders happy.
- cheap transactions make everyone happy (at least outside of EU, because inside it's already cheap with traditional banks).
- bitcoin can provide acceptable degrees of anonymity (from 0 to almost complete, depending on how you use it).
- enormous potential with limited risks for investment.
- after bitcoin gets broadly accepted by the people and it's price stabilizes, it will offer high levels of reliability in case of economic krash.

Cons:
- price fluctuation frightens average merchants (this will get better as bitcoin gets more and more broadly accepted).
- requires some learning time.
- implies stress, as you are your own bank, which can be very stressful if you're not tech-savvy
- slow confirmations.
- the anonymity is a double-edged sword that makes life easy for black markets (as well as terrorist groups).
- we are still in bitcoin's early days and no one could tell for sure that's it's not going to krash if people lose faith in it.
- the economic model of bitcoin is a deflationary one and can't ever be modified but there's no consensus amidst econmists as to whether this system is practicable in the long run.

Cons seem to be more numerous then pros but they are, for the most part, of lesser importance too (slow transactions and learning time are no big deal), at least as the situation is now (let our descendants worry about what future economic models will be).

The advantage of bitcoin is that you have a type of freedom with your money, less fees on higher transaction and fast when comparing to western union.

The fluctuative price is the main reason why people still scared with bitcoin, but for me we can used that thing to get profit.. 

I don't think old people will ever get Bitcoin to be honest. My mother still has no idea how to check email, my dad barely knows how to use a computer, let alone grandads lol. I think the older generation is too separated from all things technological unless they grew up studying computer science or something related to their job.

Well for me I save some money and 25% of that I buy bitcoin. What I like is with holding with bitcoin that the price increase that is one of the advantages that I like and also with the low fees.
