I'm thinking, Maybe they could add a feature of sending Crystals to other players in the gift section. So you would go in the garage and go in special, then click on Crystals, then you would have to type two previously set passwords in the right order, then you select how much you want to send, then if they accept the gift, it subtracts it from your Crystals and gives it to them. if not, you keep the crystals. If you don't set the password, you can't use this feature. (Idea as a main mission, set password for crystal sharing). Thanks for your time :)
