Just buy as much bitcoin as you can (obviously that if you do not trust in bitcoin, then dont buy, dont be that badass)
I am looking to what is the best way to get the most for my money?
Are you crazy? Seriously you are asking this crap? You can easily lose all your money in one of those sites, they are just pure garbage who are claiming to be a serious bussiness, dont even put your money in one of those ponzies if you do not want to lose your money.
I am looking to Mining contracts?
And what are you going to do with your bitcoins on ebay? They do not accept this crypto, there is nothing that you can do in order to make profit using bitcoin in there.
I am looking eBay?
