If you want some crypto currencies you can get some below.
If you don’t mind spending some time clicking links which you do anyway when ever your on the internet. I’ve been using Bits For Clicks since February 2014 back when it was CoinAd.
You can also use Faucets. If your going to use a faucet your going to want to get a micro wallet.
Once you get some crypto currencies you can invest in some hashing power to get even more. You can do this with a cloud mining service.
If you own a website you may want to try joining an Ad Network that pays in Bitcoin.
If you have the money to buy crypto currencies I would recomend buying bitcoin and then exchanging them for the crypto currency of your choice. You can buy bitcoins at the following locations.
