When you have the spellbook, the basic way to earn in the game is to rank battles. Every battle, you will win Dark Energy Crystals or DEC. DEC can be used to buy cards and other in-game assets or you may trade it to get real money.
Related to rank battles, you can earn cards, DEC/credits, and potions.
These items can help you in the game in long term. Cards have different values which you may sell to earn more DEC while you may use credits for rentals or card purchases and other in-game assets.
If you are able to get a hold of a high quantity of a certain card, you may offer them in the games rental market. Every card offered in the market has different rental prices and you will earn DEC by letting other players rent your cards.
If you have some funds, this is a good way to earn in the game. Buy cards at a lower price and sell them with a markup. I remember when I joined the game, Furious Chicken is at $2 and now it is selling at $30. That is a $28 profit. I suggest buying cards in bulk to other players to get a discount or on third-party sites like 
You can earn money by making blogs about the game. You can even have multiple incomes just by making one blog, just use the hashtags #splinterlands #splintertalk #peakd #leofinance #oneup. By having these tags, your post will be cross-posted to three (4) sites namely splintertalk, peakd, leofinance, and of course oneup.
The more people who upvoted for your blogs, the more you will earn.
The game has a unique feature, the tournaments. These tournaments are initiated mostly by groups of players. By participating in these events, you may win big prizes. There are different tournaments. It may be per rank tier or open to all players. Depending on the event, you are required to have an entrance fee to join in. Prizes may be in the form of cards, DEC, or SPS.
There are lots of giveaways set either in discord or by other players.
In discord alone, the game's official server has some giveaways aside from other players who promote their events and channels. Giveaways may be in the form of DEC, cards, SPS, or even delegation. Decipher's Clan discord server even has these for giveaways. DEC raffle or Chaos Legion.
The server is headed by 
By having funds or assets, you can start trading.
I have used this and earned a couple of cryptos.
This is very basic, buy low and trade it high.
It may take some time but the more assets you trade, the higher is the profit.
This is a passive income wherein if you have enough in-game assets, you gain SPS daily for a total of 365 days.
With current total assets of 45,772, I am able to get 6.01SPS daily which is equivalent to $3.10. You are compensated by just having in-game assets.
Another feature of the game now is the voucher airdrop.
If you have sufficient SPS staked into the game, you will be rewarded for a voucher.
This voucher can be used to buy pre-sale packs but for most players who can only have minimal or less amount of vouchers, they trade/sell this.
Currently, one voucher is set at $17.99.
Even if you only have a fraction of the voucher, you can still get a value out of it.
0.5 voucher will give you $8.995 which you can use t buy 2 packs during the regular sale for Chaos Legion.
I know that a lot of players are having some concerns because of the nerf given to Novice-Bronze 3.
If only they know how to earn not only from ranking, they will surely be delighted to know more of this content.
