I’m interested in getting the ruby steel card. Which is $400. Does the 180 day holding period mean you can’t sell any of the CRO till after 180 days? Also I’m planning on getting the jade green ($4K) card eventually (hopefully this year). Would it be okay to go ahead and apply for the ruby steel card and stake $400 and work my way up to the jade green card or just wait till I can stake $4k all at once?
