This card has tanked 63.7% this week and 88.5% this month, so if you're holding stock it's worth deciding soon whether to list now or sit tight for a floor. It's already hit its 30-day low of £6.71 after trading as high as £58.71, which is a brutal swing—though at £20.81 now you're somewhere in the middle of that range and the momentum is still downward.
