A few questions/concerns I have:
1. What would happen if a card value shoots up and puts a user's current open trades over their monetary limit? Would that trade be automatically cancelled? Would they have to cancel some trades in order to bring themselves down into their limit?
2. Placing a limit on users could hinder the growth of userbase. For example, my 2nd trade (1st I started on the site) Included my Tropical Island. According to the new rules proposed, I couldn't even include that in a trade until Level 3, after 3 months on the site. I personally wouldn't have even bothered with deckbox and would've ended up using PucaTrade as my primary trading site. Which hurts to say, I much prefer Deckbox. Saying "you're not allowed to trade for actual value because you're new" discourages new users. "Sorry, I'm not allowed to trade my Arid Mesa here, Deckbox says I can't be trusted to trade that yet."
3. Having to essentially buy level 4 is a bit ludicrous in my mind. I've traded for thousands in cards here, have no negative feedback, have fixed all problematic trades, and put in my dues as a new trader having to send first. But since I've never been able to pay for premium and find better deals on cards elsewhere (like users trying to list $3 rares for $100 in an attempt to make it appear like the card is spiking in price), I'm not allowed to have level 4? I have to trade with restrictions? I'm currently aiming to finish a legacy deck, and I wouldn't be allowed to finish my deck here, because I need Imperial Recruiters.
4. I get the idea, of attempting to provide some form of security for users, but ultimately, it's not Deckbox's responsibility to limit users to provide some sense of security. If a trader doesn't ask for a brand new user to send first for their own safety, a basic precaution, while the scammer is scum and is a horrible person, the trader being scammed could've taken such a basic step to stop it.
TL;DR Good idea in thought, Terrible execution, driving members away with absurd restrictions.
