When I recently saw BTC cross the old April peak of around 266 I was pretty sure it had a way to go higher before crashing.  My reasoning is as follows.  In April when BTC hit 266 and crashed it had only been trading above 200 for like 2-3 days.  The price was just going crazy.  When we recently crossed 266 we had been trading above 200 for like two weeks.  We did not merely tap the 200's like April.  This time the price rose more slowly and approached 200 and retreated a few times before breaking through.  Now we are trading above 400 and making new record highs every few days.  At some point (probably after a big day with $60-$100 up move) this will end for awhile with a crash but I don't think it will crash down to fifty dollars like in April.
