Growing your collection power with SPS is smart too! In the end if you want to play the game having cards of your own is the best strategy :-)
I would recommend staking a percentage as well as in the future without SPS you'll miss out on a lot of opportunities and SPS will become more expensive than it is now. But that's just my 2 cents, I can't look into the future :D
Yeah i've staked some percentage as well, just trying to get around with what I have to maximize for the best of options. Congratulations to you. Whew!!!!
Ohhh - good for you! I think you're doing great, glad you decided to spend time on Splinterlands, the game is still early and has much to offer the next few years :-)
