The theory is also that people are taking profits at the top and selling Alt coins to fund the next buying phase when the price
take a dip. The dip usually trigger some bots to protect their traders investment, so it takes some time for things to correct
after this happens. When the human behind the bots take over, they buy in again on the dip. Buy low and sell high in motion.
Yes good for them, as for me I didn't sell anything and just hodl all the way and not sure if that was a good idea since I bought altcoins when they were all in green
