actually, many ways to earn money from cryptocurrency. I divided the way into 2 chapters.

-if you have enough money as capital
 1.you can invest the money you have to join ICO program from an altcoin. which later if the ICO that you follow
    successfully you will get multiple benefits with trading (I will explain in no 2) altcoin
 2.Trading, basically trading is buying and selling. here I explain you can do trading and get profit after ICO
    program that you follow by assuming if ICO that you follow success, you can sell altcoin which you get from
    ICO at very expensive price. or you can simply trade altcoin with some money you have. but here you have to
    be careful in observing every up and down price movement of all altcoin
 3.mining, little that I know from mining because until now I never though mining to earn bitcoin or altcoin. for
    this you can visit https://bitcointalk.org/index.php?board=14.0 or https://bitcointalk.org/index.php?board=160.0
   
- if you have absolutely no money as capital
 1.faucet, you can get bitcoin or altcoin by just filling captcha from a faucet website. search in google, so many
    faucet to get bitcoi or altcoin in there
 2.Bounty hunter, you can become a bounty hunter to get bitcoin or altcoin which you can exchange into money.
    here you have to promote the project from a cryptocurrency and get paid for it
 3.mining, for mining in this chapter I explain the mining of a website where we do not need capital to buy
    hardware for mining. we just need to create an account on that website and hire hashpower from that website.
    but for now this is not I recommend because now a lot of mining sites are scam

hopefully my explanation is easy to understand

In my opinion for the beginner the best idea to make money through Bitcoin is signature campaign. Because it is less risky and more effective method to make money from Bitcoin . Bitcoin price is highly volatile, in my opinion if you have enough knowledge about this  then you should invest in it. If you have enough money then you can buy some Bitcoin from various websites. If you want an stable and effective way to earn some money then you should do Bitcoin mining. For the beginner cloud mining is best and for those who  have some knowledge of mining then they should try hardware mining.  

There are many ways to make new crypto. You can try mining . can trading some crypto currency. Signature and many other campaign can give you a lot of earnings. You can also hold bitcoin to earn more profit.

Buy coin worth and keep them, if your coin project is successful and you will have money, or you can join ico if you succeed you will also have money.

The first step to making money about crypto is getting and assimilating knowledge and valuable information about the crypto world. No one, who is considered wise, ever ventures into any business because it is the wave or thing in vogue. The next thing to do is to seek someone who genuinely can guide you who has a proven record of the cash he's made. Understudy him and hear his faults and leverage on his strength.....With this you are now ready.

you can earn money in crypto with a zero capital.
Join in airdrops and bounty. Just need your time and effort to do all those things needed in airdrops and bounty.And of course you can do also buying and selling cryptos to earn.But before doing all these things feed yourselves with knowledge.Start to learn the basic one.

the most appropriate way to earn money profits is to trade because the trade can provide multiple benefits.
and if you want to get a free way is to join the bounty campaign and the results you can invest.

If you have a large enough capital maybe you can buy the coins you want to invest. But if you do not have the capital, you should join the ICO project. Because the results of the ICO project is very good for supplementing your income bit by bit.

The most convenient way to earn money is to follow ICOs that offer commissions for their holders. There are tons of ICOs and you need to be very careful.
You can as well keep an eye on the exchanges and keep trading cryptos and knowing when to purchase or sell.
The easiest way is to open an account at an online exchange and wallet which offer referral commissions. You will get free funding by your referrals deposits.
These mentioned above are for the average user that does not have the resources to mine. You can always mine in new cryptos and earn some good values and then exchange them for something bigger.
