So, what is "there" considered a fair ratio BTC/LTC?
I'm frequently trading btc for ltc and I can tell you from experience the borderline where you find buyers/seller is about +10%, meaning you offer a deal where you offer 10% more btc than the current value to get ltc.
For those who marked my offer for cards as a scam only human understanding. They are totally free to dislike it, but how it can be a scam only God knows. I don't have a clue on how much they can be worth.
Cards are currently worth the amouznt of stars on the card time 0.5 sat minus 20% and it doesn't make any difference whether you offer small or large amounts, above this price you won't find buyers.
What I do is simple, I just count how many cards I'm putting on sale, multiply each card by the amount of stars it has and then in the end I multiply the result * 0.4.
