Trading long  Bitcoin on breakouts is not a bad move for me, especially breakout on an all-time-high. Some people also tend to open a long position on the pullback after the breakout, but sometimes it is not going back anymore after the breakout. So, it's difficult to be sure about this.

About the leverage you used, it is good for me, having low leverage on this kind of trade is good, make sure you don't forget to put your stop loss and price target based on your risk:reward ratio.
