Thanks for your interest! We've hit double digits so I've started cold-calling A16Z and other investors. You'll get it by email, but we have Twitter and Facebook sharing links to allow you to easily brag about your financial prowess and gambling ability (see here: https://buyblockpaper.com/View/5). Of course, if you tag us on Twitter, I'll retweet anything and tell everyone how smart you are (see here: https://twitter.com/BuyBlockPaper/status/1490047224688132098)
You should add the meta tags for social networks on the viewer page. The summary_large_image version should be cool. You can test the feature here: https://cards-dev.twitter.com/validator :).
