I have two questions for discussion. Why does bitcoin occasionally drop hundreds of dollars in mere seconds. I assume a massive sale of coins has taken place and that makes it move. But I don’t know that for sure. Secondly and more importantly. Why do many other alt coins drop huge amounts at almost the exact second bitcoin does. I have seen this happen many times and it always happens together and at the exact same second which rules out in my mind people watching bitcoin and selling equally large amounts of alt as if all happens too quickly.
