Bitcoin curve looks as if a Head and Shoulders (bearish) pattern with a resistance around the 4500 level could be forming. If so, it could fall back again to the 3000 level.
When it falls through the 3000 level, a Head and Shoulders pattern on an even higher level could be formed, going all the way down to the 2013 ATH, with the 3000 level becoming a new resistance like the 4500 level now.
