[ask] What would you do in my shoes?

So I'm a level 9 player that has in my opinion peaked In trophies without spending more money I think im finally at the "wall" , I'm sitting at 3057 trophies , level 6 rares and 9 commons, the epics I use are level 3 and 4.

My trophies usually fluster from 2800-3000 and now sitting at 3057 with so much of the season to go I wonder .. Should I just wait it out and collect those 57 legend trophies? Who knows what they'll be used for in the future but.. I know im most likely going to just fall back down and if I can beat this trophy count it won't be by much , so do I sit and collect my legend trophies to always have the memory of this moment before I inevitably drop back down below 3000 maybe not being able to make it back before end season ... Also .. Do I spend money now..? And if so how much money are we talking that's needed to progress to say .. A steady 3200 trophies ? I've spent about $150 way back in arena 5/6 a couple months ago before SMC's came out . I have gotten both my legends from normal chests (free chest and gold chest)
