Yeah, every trade is a taxable event to US persons. Whether that is buying coffee or litecoin. It is property according to the IRS.
Even if you thought you could get away with the like kind exchange rule, you still have to report every trade individually on the exemption form.
If it were classified as a stock, you could just report net gains and losses but not so with property.
They have made compliance nearly impossible so unless someone passes a law to exempt transactions prior to a certain date, a lot of people are going to owe back taxes and penalties if not jail time.
