Hi everyone!

I'm Gil and I'd like to start investing in bitcoin / buying bitcoins. However, I'd like to ask few questions before I set my self off to this adventure.

I live in Australia (don't know if it matters for Bitcoin stuff).

Back in 2014 I opened my first wallet and got a $1AUD from a colleague. Currently it's worth is mBTC2.26 which is about $6.92AUD.

The android app I used is simply called Bitcoin.

Now, here are the questions I have. They probably sound dumb to you, but bare in mind, I'm very new to this

• Is there a good Desktop bitcoin app?
• Can I sync between my Android app wallet to a desktop app wallet?
• Are all wallet apps the same? or do some offer unique functionalities?
• Is my wallet unique to the app I used to create it? I mean, if I install a different Bitcoin app, would I be able to have my wallet appear on the new app?
• Is it possible to share the wallet with my spouse? I mean, if something happens to me, I'd like her to be able to access the wallet and keep the Bitcoins
• If the answer to the above question is 'No', then what would be the best way to let her access the wallet?
• Let's say I (and all of us) became rich from Bitcoin investment, how could I change Bitcoin to dollars in my bank account?
• What is the best way to purchase Bitcoins? I'd like to start by purchasing 2 bitcoins. Is a purchase method unique to the country I live in, or is it done via the app I'm using?

For now, these are the questions I have

Thanks everyone!
