About the MCs though, I'm still rather confused. So when would be a decent time to buy one (without the use of Gcash) and to sell it for profit?
I used to vend on the RIG items as well, as soon as they came out the prices normally jumped around and I did pretty well but I never actually understood what was going on. The prices just seemed to jump and I could never really figure out the pattern sweatdrop
With MC's you have to use your basic understanding of the Gaia community to determine what will be popular or not. The best time to snatch them up is immediately as they are opened. Once you see if they look like a popular item or an item with potential to be popular, grab them all before the price elevates on them. If they don't look like a good item, then simply pass them by until next month.
If you like to gamble, you can also invest in sealed envelopes just before they open. The price for those is always a standard average, so if the item turns out to be a good one then the price can jump right up. Or another thing you can do is look for sealed envelopes as soon as the item is opened. Then you will know if the item is good, but you still may find some underpriced Sealed Envelopes that are still at the standard price and get them before they change.
A good MC can also be good for hording or long-term investment though. If you see an MC will definitely be popular, it may be worth holding on for a few months. When they come off the market, the price will only continue to grow as long as they're useful for avi-making.
