You can start by creating an account here. make a post until you rank-up to junior member. then join a Bounty campaign. It's the basic thing that you can do in cryptocurrency without spending a penny. you can also start creating a wallet in Myetherwallet. but make sure that you're entering the correct website. There are a lot of phishing websites nowadays. so you should be very careful.
It is also what I started and the money you can earn was based on how you will use, either getting profit or buy some asset. In this forum, no need to pay too much because the capital you need was the time and your knowledge about this crypto. But just read some article or any thread regarding rules and regulation to prevent from wasting your time in this forum.
