&gt; Unless you are also auditing all the code you use for software that objects with Bitcoin yourself<p>As I mentioned in another reply, compared to existing electronic monetary systems, an open source one will always be more trustworthy than a closed source one.<p>&gt;Bitcoin involves trust in the mining community<p>To be a part of Bitcoin, miners need to follow a publicly known protocol that is easily verifiable by anyone using math.  Additionally, miners never have direct control of your money: they can&#x27;t spend it on your behalf.<p>I think the only point you have there is that you must trust someone somewhere to mine Bitcoin.  And as long as there&#x27;s a profit to be made, someone probably will.
