I must say setting the limit at 0.75 was a very good decision from me. It has helped keep me having too much fees or having too low transactions. The number can be kept at 0.50 too but I think 0.75 is a perfect balance so far. Based on 1 week worth of observation, I found this limit suitable for me. I hope setting this limit also helps the BCH network transactions. What limit have you set? Are you comfortable with it?
