To obtain cryptocurrency, first, download a wallet such as Exodus. Storing your currency on a locally encrypted system like Exodus means no one can steal your money. However, if you lose access to your device AND your back-up phrase…. You will lose all of your money. Also, if someone else manages to steal your back-up phrase…. They can steal your money too. Be very careful with your back-up phrase. 

Then purchase cryptocurrency through coinbase or localbitcoins. After you have a Major cryptocurrency, you can exchange it to other currencies instantaneously and easily through shapeshift.
