I will upload a portfolio soon and I am here for more than 2 years ...
But it's nice idea to buy a Copper membership.
Two years but there are not much contribution from you in the forum. I think any forum member or crypto projects will only think to ask help from someone who has contributed in the forum and have a good track record of working with others.
Copper membership may help to showcase your previous work but you still need a good rank and reputation.
