First of all if you don’t already have one you need to get a Bitcoin wallet, this is a digital wallet that stores all the Bitcoins you earn.
To get a wallet go here and choose the best one suited to you.
Once you have done this and have your wallet set up you are now ready to receive bitcoins!
The easiest way to get Bitcoin is to buy them, this may not be the cheapest way but if you invest at the right time this can very profitable. If you want to buy Bitcoin there is many websites out there that you can do this but always remember to check out the site before you send any money.
My suggestion would be to use www.coinbase.com it is one of the biggest and most trusted exchanges out there and it also can be used as a wallet,
