So a few different supports or buy targets.
1. The trend lines
2. The fib levels, as you can see they have touched a few times. [.5 and .38]
Perhaps put buy orders in all 3 (trend line + .5 fib + .38 fib)
If 2/3 supports dont get hit at least you still have BTC or Fiat left for next time :) Shouldn't get greedy!
Thoughts ?
