I would recommend you use 1btc to buy 10,000,000 MTC then hold everything till december and see how it pans out. https://marineco.in/#prices  I know it might seem a bit to risk on marinecoins, but it is being revived and there really is no downside to this. I really believe there is more room for MTC to grow than there is for BTC, given the market caps of the two currencies and their relative prices.
