Fun for now, not sure it has the staying power
The coin system sometimes fails to pay out, or only pays out after a significant delay, which is frustrating if a timed sale or limited run item pops up. Ive been able to grind out the coins for most in less than 30 minutes, but if it takes two hours to show up in my balance, then its neither rewarding nor encouraging.
I do like the trading system, and am no more put off by "rude" or "difficult" collectors than I am in real life-- life isnt always fair and people change their minds about trades in real life all the time. Being disappointed by failed trades and wasting time negotiating with someone who backs out or changes their mind about the offer before accepting the trade is just part of being involved in collectibles.
Having said that, the trading system becomes more crucial as it becomes more and more difficult to earn coins through commercially sponsored tasks, which forces players into a pay to win system at times; it can be very confusing initially what to spend the coins on, turning it into a pay to play situation for those unfamiliar with how these types of trading systems even work, let alone learning the less-than-intuitive basic mechanics and user interface system.
A big positive for the system is actually having decent virtual content, which, for now, makes the frustratingly buggy coin drop rewards turnaround time, the clunky app mechanics, and the confusing interface somewhat worthwhile. Time will tell if the app has the staying power to keep collectors eyes on the prize and their minds off the systems distracting frustrations.
