BTOG is dropping quite a bit. It started at $3.87 in the morning, but now it's fallen to $3.40. That's a decline of over 12% during the day, so it's a fairly significant move. Since it's a cryptocurrency-related stock, it probably reacts sensitively to market movements. In such cases, it might be necessary to observe whether there's some news or catalyst behind it, or if it's just selling pressure.
