How to receive Bitcoin (BTC)
First of all you need a Bitcoin address for receiving Bitcoin. You can either use an online wallet like SpectroCoin and StrongCoin or download the official Bitcoin client Bitcoin Core. If you want to download the official client, you need to wait several hours after installation, until all necessary data (about 100 GB at the moment) is downloaded.
On mobile devices you can download the easy-to-use Bitcoin App for receiving and sending Bitcoin. With this app you can easily generate your own Bitcoin addresses and you can send Bitcoin by scanning a QR code or by copying the recipient's Bitcoin address.
When you have a Bitcoin address to receive Bitcoin, you can try earning Bitcoin to test your new wallet.
