The reason why DOT behaves like BTC may be because like BTC & ETH, many institutional investors are holding it. It was one of the first big winners last year. After plummeting straight down with decreasing volume, I think DOT is ready to reverse. It was recently rejected by the 23 pivot so it may go down first to retest previous low before a big rally. Note the big trading range so the risk to reward is great at this low. Better see if it breaks above 23 soon. Not trading advice
