I have said this same thing over and over and over again in numerous posts in numerous threads and yet people don't seem to get it. There is literally no limit to the amount of accounts you can have so you could continually start account after account doing the pyrate bay quest/and or finding and getting all the hidden gralat chests in the game and buy those preset chests and set them in there respective houses for your main account to keep getting. Yes its very time consuming and everyone could do it.
Using that method would open the door for people to get rich faster and cut down on the need for people to buy gralat packs. So they will not let it happen. The company that owns the game wants and needs to make money so they will never introduce something that would help players make a ton of gralats easily.
To summarize there can never be and will never be a way to trade items,have our own shops,or transfer gralats via chests or other means because people will scam and or abuse it and get rich fairly quickly without needing or using gralat packs so the company wouldn't be making money. Don't get me wrong I like the idea it sounds great but it will hardly ever be used for what the original post suggests what it could be used for instead players will use it to boost their own bank.
