The Cardstack team designed cards to be carriers of truth that can assemble with other users' cards to create larger experiences that can be shared and reused.
Today's CARDSTACK decline is 6%, this was followed because the price of bitcoin and ethereum dropped dramatically yesterday, even though CARD has made the latest update on its WEB 3.0 but the price is still sad
Don't worry about the price. The team is in BUIDL mode right now and the markets follow BTC's lead. It's a long-term HODL.
