I see lot of post about monopoly Go and giving it a try

I have no idea what to do really just roll the dice and upgrade my buildings with $$

Any tips or or what is valuable and what can be tradeable?

The sticker album ends in like 3 days, don't try too hard and use up all resources until after then as you'll lose progress in albums after the reset. If you can finish up the earlier albums that dont require anything higher than 3 stars in preparation for next season. Generally early on 4 stars are pretty valuable, and 5 stars are always valuable.
