VALUATION
Based on recent similar sales in the last year with as similar as possible features and excluding outliers... bitcoinstream.com sold for $354, and bitcoinjunkie.com sold for $409, and bitcoinspot.com for $565, and bitcoinmag.com for $635. So based on that we'd guess a spread within that range $300 to $600 as your most likely spread. This is backed up by an independent valuation using the Rosener valuation method which put the domain worth at around $614 to an end-user.
EXPERIENCE
I'm not an expert at Crypto domains, but my understanding is that everyone thinks they're super valuable because it was trending for a while and there were a few big sales... but from my own personal experience... I've listed the below on over 100 marketplaces:
BitcoinWholesaler.com
BitcoinImmersion.com
BitFaucet.net
BitVat.com
ChainSumo.com
Coingular.com
CoinFoto.com
And I've still never even had a single offer. I'm thinking for every 100,000 crypto domains out there... there are a few big sales... but the majority just sit in people's portfolios.
YOUR OPTIONS
1. Hold on to it, list everywhere, and wait... possibly years for an End User to pay you the very rare prices that make domaing worthwhile $2,000 to $20,000 depending on your luck, guts, and skills at negotiating. And you might never even get an offer... so don't get blinded by the big figures... with these kinds of domains, its like buying lottery tickets. You could of course list for $300 to $600 and hope it gets noticed... but as I've not had offers... it's not looking great.
2. Some domainers are open to domain swapping... so you can either try and trade it for a domain that you think will do better... or several domains... thereby growing your portfolio, and increasing your chances of a sale.
3. Go for the tiny profit and sell to a reseller... you don't make big bucks, but you've made your first profit, and passed on your risk to someone else.
If you are open to number 2 or 3... feel free to message me... I've not made any crypto sales yet... but who knows... maybe someday right
