Hi,Mary
Your domain name is not premium but have good value, if you want to sell it at good price, then find end user.... Not on domain auction platform. ..
You may get around more then $ 300
the .COM isn't developed so it's hard to tell. There were a total of 3 recorded sales with keyword "eExchange" in .NET extension in past 11 years, the most recent being in 2015. The sold domains are still Undeveloped and one of them is available for registeration for reg fee that was sold for $268 in 2007
This is one of those domains that will do good on $1 start Flippa no reserve auctions IMO. It has potential if it's developed especially while Crypto is still somewhat hot.
