To me, purchasing BitCoins is always a good thing; but I am always afraid; at the same time, when doing so. At times, you can even find interesting offers on non-bitcoin forums and marketplaces; but in order to transfer those safely, one needs a system that lets you trust a total stranger. BitHalo seems to be offering just that ( http://davtonia.com/halowiki/index.php?title=BitHalo_-_The_world%27s_first_smart_contracting_client ), but I am still not convinced. Any thoughts?
