I have property investments too. It's traditionally a slow, safe way to grow your money. It's also an investment that you can highly gear; most of the money is usually borrowed. Traditionally it's 5:1. Not bad at all.
What was your out-of-pocket investment to make that 7-8%? Looking at it that was is it still 7-8%?

No-one is in charge of bitcoin. I'll see if I can't explain how I understand it, both to the layman and myself (correct me where wrong):
It all runs on a
blockchain. There's a video above that explains what a blockchain is very nicely, but basically it is a
ledger of transactions that is nigh on impossible to alter. The step required to generate a valid hash for a chunk of transactions (I think it must happen in chunks) is very processing intensive nowadays, as the blockchain grows and grows. This is called mining.
The
mining is what is actually running the entire system. It is distributed across every machine in the world that is mining. As a reward for mining the miners have a chance of solving the hash and getting a bitcoin for their efforts. I think there's a small something given to those that contribute but don't solve or something too, not sure.
So there's your incentive for setting up a bitcoin mining operation and providing the processing power required to run al this, completely openly and decentralised.
Note that you can download the entire bitcoin blockchain yourself. It's well over 100GB now. Waaaaay past anyone mining at home with a single PC.
Now, because you can download the chain yourself... can you edit yourself. Yes, you can. You can change any transaction in the ledger to whatever you want. But it won't generate a correct hash. And generating that hash would take... a very, very long time, by which you version will be out-of-date. And even if you could corrupt the ledger and generate a hash instantly your version will not match all the other versions out there. That's bitcoin's inherent
security and why banks are using blockchains too now (see: ripple).
And that's... pretty much it. As a currency system its advantages are clear. As for its value I must admit I am a little confused as to how the value
first started. What kicked it off? Once more and more people start accepting it as currency, which is obviously happening, it goes up in value.
Supply and demand. By the way the number of bitcoins is limited by design. And they get harder and harder to mine. I think it's capped at 21 million. Artificial scarcity, exactly the same way diamonds are artificially priced.
As for accepting bitcoin as currency I will happily accept it @ 1CCvT3FTUAoQ3RCKwYAcoJfZ6AVyiNsbki
I'll accept diamonds too.
Ease of use. I suspect a lot of the trade recently is people getting money out of China, or Russia. Used to be $US. Has to be some currency. But using bitcoin you can transfer money, pretty much anonymously, to anyone in the world like that [snaps fingers].
Securely too. Take my wallet address above there; if you get one of the characters wrong the chances are you have a completely invalid wallet address, and the transaction won't work. Overwhelmingly so. Unlike a bank transfer where you get a number wrong. And nobody can pretend to be you to take your wallet; Identity Theft. If you make a "cold storage wallet" correctly then only you know the address' corresponding pass phrase.

So that's my understanding of it. It's all explained further (/much further) here:

Here's what I said (I hope) in a snappy, very short video:
