Considering it is plural not singular, $12k is an OK offer but not quite at the right valuation. I see this name as a great brand in the crypto betting niche, which looks to have an immense amount of potential.
Retail: $15k-$45k
Wholesale: $900-$2.5k
Great Crypto name, I wouldn't be surprised if you sell this name at a retail price higher than my appraisal.
Good luck!
