Sorry, but I can not offer free samples 
I like to maintain certain level of quality, and that takes hours/days of work.

If there's, let's say, a new cool coin coming out - I would be willing to work for a bounty in terms of X amount of those new coins. I believe this is fair from my side, as I potentially will have no gain from this.

My work can be found on my Instagram, and I will aim to add more things there.
Hope you understand, thanks
