You have to find the right place to promote your services, dude. Your offer is great, but in this place 90% of people tend to seek information and discuss cryptocurrency. You're not wrong to promote here, but is it effective if you offer web design services on cryptocurrency forums?
It's better if you offer it on the service marketplace
