@exyle,
"A client will forget how much he paid (or how much discount you gave him) and will only remember who helped him and how well."
Anyway dude what you did is risky too!
#1. He will know there are a lot of alternatives and cheap than yours.
#2. You are loosing your main source of income slowly.
For me you should not let that happen! After all this is crypto world and we lives in real world!

Cheers~
