If you have already gained some experience in Splinterlands and now would like to earn DEC in Bronze 2, you will face a problem: 1000 Power. I'll tell you the cheapest solution to achieve +1000 power in Splinterlands.
Do not rent golden cards
I read of many players renting two gold cards to get to 1000 power. If we assume the cheapest offer of golden cards, that's still around $0.20 per day. This is very expensive and difficult to recoup.
Focus on Rare Cards
If you focus on rare cards, you will hardly have any expenses during the day. I currently reach 1000 power for as little as $0.03 per day. But that's because I already own some cards myself, so I only have to rent 800 power.
There are many cheap and rare cards that you can rent for as little as 0.1 - 0.2 DEC per day, which will give you 40 power per card.
Examples
Here I have two examples for you:
These 2 cards have 40 power each and with luck you can get them for 0.1 - 0.2 DEC per day. Very cheap.
So if you borrow 25 cards from it, you get 1000 power. For these 25 cards you would pay less than 0.04 $ per day. This 0.04 $ you get back quickly in Bronze 2. Depending on your DEC rate, that's about 3 wins.
Conclusion
As you can see, you can get 1000 Power very cheaply. I hope I could help you as a beginner something with it, if so I would be happy about an upvote from you.
Cheers.
