How often do you play splinterlands game?

I often play splinterlands in morning and evening. I have played this game for 2 hours every day. ERC under 50% I stop. Because I want to earn more DEC so I rent gold card, alpha card, pro card and I often play in bronze 1 rank. Each battle I only need earn about 5-6 DEC. A day my target is 100 DEC is enough. Play to earn and rest.
