Need Help Understanding Crypto Currency

Is there a site, thread, etc where I could start learning and understanding Crypto Currency? I'm mainly interested in Bitcoin andEthereum but have no idea where to start.

Yes if you google this you can learn a lot. I would recommend reading the information about this and watch the documentary on Netflix. I found that it was helpful.

Also would be useful to find out about the past of Bitcoin, like who created it and there method of approving trades.

It is also impracticable to use every day as it can only approve 7 or 8 trades each second. VISA can do thousands a second.

There is a good number of books on the topic, no? Why don't you just read one of those?
