This is festival season of many international people and x-mas is coming in 2 days and they are selling to enjoy their festival. When they come back to market after holidays, it will again start to go upward. Ups and downs come and go. Whenever a market touch its resistance level, it drops a little bit.
Indeed, honestly im one of the people who cash out some of my bitcoin not because the price drop but because I needed extra cash to buy some things for Christmas like gifts for my family and godson and goddaughter. Its a time for gift giving so its an excuse for me to sell.
