imo you should stake a price that you can afford to sell your coins.
for example lower 22k - max 37k
just a suggestion though, you do what you see fit after all...
I have already staked that the price that I could sell them is around 35k which is staked a post above yours.
The price of ICN is changing to often and I think that people can make a good money on exchanges.
What I want to save it the exchange fees on both sides and selling them for a better price.
