On top of what the rest of the comments mentioned, I guess it also depends on your objective of playing Splinterlands, is it primarily to earn or is it just for fun? For me, it's really for the fun. Any "winnings" are just bonus to me.
Of course, losing streaks are demoralising sometimes. I have lost 10 in a row too. But it is also an opportunity to see what went wrong too. For example, I would note down their lineups and use them next time.
Based on the value of your deck, it shouldn't be too hard to get to Silver! All the best!
Both fun and winnings. But nowadays both are bad in the case of Splinterlands. At least for me. This is why I decided yesterday to lease out at least a part of my Splinterlands card collection, instead of playing.
Good luck and have fun.
Have a nice day. All the best. Greetings and much love from Hungary.
