Wrong! Even prices dropped from December top, they still fluctuate. You always have a chance for day trading, if not bitcoin you can choose other coin. Take a look on coinmarketcap site, there you can see daily changes in most simple way, I don`t recommend anything more complicated then that for newcomers. You can`t trade efficiently if you don`t hold some amount on a side, except it keeps you calm when you trade (you always know that you have backup), in case you made a mistake and made wrong prediction you need to have means to do something more, I spoke many times about that, read my comments and you will understand it. Good luck for all people who wish to try to trade without holding, who risk 100% can lose 101%.
