Sadly in my view the current exchange (stocks.exchange) is holding back ITNS. As an investor and miner it's really pissing me off so much so I have changed to another coin for the time being in terms of mining so I can avoid having to use Stocks Exchange.
You do not have to use Stocks Exchange if you are investor and miner. You can mine (as miner) to local wallet (versions for all major OS available) and then hold it (as investor). When we see a real value for the coin, more exchanges will add it by own initiative.
But if you want to mine and dump ASAP, then you need an exchange. But then hardly you are investor, aren't you? :-)
