I couldn't find a signature in the OP so I'm using one I copied from someone else.

Similarly, I couldn't find a link to the Lisk coin design icon in the OP, but i found a whole page full of them in the Github.

https://github.com/LiskHQ/lisk-ui/tree/development/images

Would this image be appropriate for use on coinmarketcap? It's roughly the same size as the other design icons used for other coins on it.
