Coin expiration notice

I just be awarded that coins earned should be used within one year, but now the pts for redemption increased to 50000 for iOS. 

Assume in iOS on average you can earn is 250 (100 basic + 100 lucky box + 50 lottery), you will need 200 days = approx 7 months to redeem. The potential for coin expiration is highly increased.

Here I friendly remind everyone if you can't walk 10000 steps per day, you may very high risk to loss coins after coin expiration.
