Thanks @jrv1 for a nice, smooth and good swap.
Now the golden black dragon no longer live at my home - he is yours.
Instead my green collection grew a lot. With about 150 cards.
Good or bad investment? We will see. But It was better than sell him at the market (lower price and with a fee) and I see my deck as an investment because I deligate it out.
Last season I did get rewardscards for about 5 USD.
This season my goal is to deligate and get more than 5USD - without playing.
But will Steem go to 0,20 again I will sell some cards. Just because I think the value will go up after that - and I can buy it back and have steem left.
