DarthMo0: I seemed to have hit a wall as now all the apparel upgrades are 30k coins while my coin supply hovers between 30k and 50k.
Just because the game offers a coin upgrade doesn't mean you need it for your game. I have passed and not upgraded some options, simply because I seem to play well enough without spending the extra 30 or 50,000 coins.
Since you are on mobile, you should be or should have been working on watching those 2 credit videos to build a bankroll to upgrade your clubs from the start. Using the "coin rentals" is a great way to avoid buying clubs at the lower levels until you "unlock" better clubs that will last you longer in the upper levels. Seeing how you have reached L63 there are definitely some good options available to you that would last you until and still play well on the Legend tees, especially with the sponsor boosting gear.
As for coin bankroll management...you need to have a winning percentage around 63% or more at the level you are playing otherwise you are losing because of the "rake" or cut that WGT takes out of each coin match. Some players build their apparel around those items that increase their coin return lowering the rake but you still need to be better than 50% or you just are not making enough to build your bankroll and you are simply feeding WGT your coins slowly but surely. If playing lower stakes where your win percentage is better even though you build your bankroll slower, then play at the level that you get the best return. Playing higher won't help if you are losing more.
Also, maybe finding a mobile only club with tips and suggestions will help. While our club has a growing mobile group with some resources and tips, some clubs specialize in mobile only play.
so the short answer, use the coin rentals while you can...play in coin rooms where you are winning 60-70% of the time versus a room where you break even and are not building your bankroll, start or continue working on building credits by watching silly 2 credit videos...then make some smart club upgrades that will benefit you for an extended period of time, then you won't need the coin gear any longer and can use the coins strictly for your coin matches.
also, to offset the losing stretches you and all of us can face, try to have about 20 buy in's minimum for the coin room you are attempting to play in. otherwise, if you take a shot in a higher stakes room catch a bad run or run into a series of good players you can blow your entire bankroll fast! then you really have to grind it out or start buying coins. play smart, and strategically and you will make better decisions.
