Traditionally sell MN and go to the sunset.
I will be very surprised if it comes to the exchange.
It need to be listed on exchanges, at least one, for sure.
In opening post you have clearly stated that funds from masternodes auction will be mainly spent to get listed on exchanges:
Funds used for :
masternodes.online = 0.2 btc
tradesatoshi.com = 0.5 btc
southxchange = 1.5 btc
crypto-bridge = 3 btc
stocks.exchange = 0.5 btc
Total = 5.7 btc
The leftover funds will be used for advertising or future exchange listings
We will see how it will look in practice..
