Getting people mining it is as simple as putting up a sufficient amount of BTC at whatever price it takes to make it profitable for miners.
And who is going to provide this BTC? Or in reverse, at the moment, less than 1 Bitcoin worth of BTM would crash the price on Bittrex to 1 satoshi. $200 would currently turn BTM into a worthless coin. I think a few of you slept through Economics lessons at high school.. If it has no value, no one will use it.
Someone dumping on Bittrex wouldn't result in much of a change as the price would readjust to whatever the market felt was a fair value at that time.
Plus hopefully Bittrex will delist it soon and we can have Poloniex again as the central point of trade. Having a thin market with no volume like the one on Bittrex doesn't add much value imo. In the future when there's demand and volume I'm sure Bittrex will have no problem readding BTM if needed.
