I know that dec was cheaper when it came to the pure airdrop points, but in my opinion, dec was also the greater loss in value to be expected and with cards you could still earn money at the time with rent and play, so I came to the conclusion, dec is indeed at the time of purchase more efficient, but in the end probably not!
i think i'm not the only one who has gone down this train of thought....
I am curious how it will develop!
