When market already move up quite high, many novice traders will jump into try to make a few bucks from believing that its gonna continue like it did before. \
market is now dropping in price due tto thos who bought at the bottom before the rally are out of the market.
better to wait for the market to really bleed down before entering in. when everyone thinking it is going to drop in value, and start selling massively thats when you have to buy from them at a discounted price.
