Great opportunity to dump STEEM for HIVE. The only question is how far the pumpers are going to go and whether to hold out for a higher price.
Personally, I'm happy with parity. If it lasts for 12 more weeks I'll have doubled my vests prior to the fork!
The opportunity can be for sure as you said in case you are planning to use just hive, else it is a nice time to hold on and use both chains to increment the profit as much as possible
