Why do you use Bitcoins?

[Kazimir]

I like bitcoins because they are shiny ! 

I fully agree, sir. Best reason so far

[binspac]

I use them because I'm a nerd.

[adamas]

I use it to contribute to a better world

I use bitcoins due to it's deflationary aspect and well thought out system of currency.  It is unlike any others and to jump into something different is quite fascinating.

Mining is another thing.  Due to its decentralization aspect I can also print my own money in this currency.  That's another factor to put in.  The people can shape the currency without any government intervention.  In this way, people have freedom to what they want with this currency.

Pragmatism:

     1.  Efficiency.  Transactions that wouldn't have been worthwhile, now are.
     2.  Versatility.  I can afford to transfer funds in ways that would have been nearly impossible with previous methods.

Intellectual Curiosity

Ideology

Anonymity is extremely important in a world that seems to become more Orwellian every day

I use BTC because its simple, practical, and I think will be around for a long time.

[Raralith]

Nothing right now, just savings them up, and buying some to bide my time. My personal opinion is that physical currency can't survive in a digital age, and BC's have survived long enough to possibly survive for the next decade.

24/7 irreversible payment processing at minimal cost within minutes to hours.
Don't know of any other payment system which can achieve that feat online.

Money.

[Mr. Coinman]

It's much more efficient than using fiat currency. And of course, the anonymity Bitcoin offers is always a plus.

[MadSweeney]

At first I thought it was because of the crypto stuff, the excitement of the market, or anarcho-capitalism. But this guy explains it better than I do http://suitpossum.blogspot.co.uk/2012/06/block-chain-of-infinite-mystery-what.html

Seems that having a (potentially) anonymous, decentralised currency makes for a better world. Sounds good to me.

[jadaiswel]

I use bitcoins mainly for silkroad

[avengre]

I use bitcoins to allow an alternative low-fee transaction on my website...

Because paypal is evil.

[MichaelBliss]

To thwart the central banksters plans.

[taplak]

it's easy to send money around the world 

[Hunner]

1. No fees or regulations by a 3rd party
2. Interesting options for the latent trader wanna-be in me
3. If it catches on, I would be highly supportive of this.
4. It's geeky

I just wish that I could use all of my IRL time to chase this and read everything and play in all the fields. But real life calls, and is what is currently funding my BTC interest.

I'm particularly interested in the alternative value structure of the bitcoin universe.  Though I'm fully aware that the USD or other internationally used (and state supported) currency took its initial value as being inherently related to some non-material value of gold, it seems that the precious metals model still exists in the layman thinking of where the value on money comes from.  Bitcoin presents what appears to be an entirely different value source, from computer labor, which allows for an interesting competitive twist, especially as the capital costs to gain entry to the "mine" are relatively low.

Aside from the theoretical interest, a non-authoritative and seemingly fraud proof currency that has the potential for near total anonymity could facilitate larger world processes than just circulation of a new currency is something that I'm not just going to brush aside without a first-hand look at the inside.
