I'll go a bit deeper on market volume for next edition, this is indeed something I only touched on but could write more on the subject for sure. I'll see if I can do a volume probe for next week!
A great marketplace to check out is Tokentrove.com, it's currently the biggest platform for GU cards.
Cool thanks. Fun times for GU. I'm wondering how things will level out after first phase and whether GU will remain a place for market speculators who buy and sell... or become like Splinterlands where the market is mostly for people to buy and hold. There's only a few people who buy AND sell. Less volatility probably means less speculators. I've peaked into the GU channels from time to time the feel is that there are a decent amount of speculators... which of course is very fun for a market.
