is the value of my holding reflected on hive engine the real value if I decide to sell?
Nope! People try to buy on the low end of the 'real' backed value, but the truth is the Hive-Engine market is somewhat disconnected from reality.
If you need to sell, reach to me and well arrange a deal (take as reference the median 'backed' price of the last 10 days minus a 2-5% fee).
Thanks for your commitment!
