P.S.: Almost everything is a taxable event as it involves "using" the actual value of BTC which is different than when you initially acquired it. The only thing I don't agree is that "moving the coins out of coinbase" is a taxable event. That doesn't make any sense.
Where is the source for "moving coins out of Coinbase" as a taxable event?
Would this mean if the coins were bought at, say, $1000 and then moved out immediately at $1000, then the gains are effectively zero? Or that I could even claim a loss if the price dropped?
Would this also mean that the further gains to $10,000 are effectively tax free, because, double taxation and all?
I don't know what's the source as I don't even agree with that interpretation.
COnsecuently, no. Also, please note that claiming a loss usually require a bigger deal of proof than claiming (and paying for) profits. There's nothing tax agencies hate more than people claiming losses. You better document it PERFECTLY and without doubt.
I think you don't grasp the concept of capital gains. Any time you realize a gain you need to pay for it... for each subsequent increment/gain.
In your example (if we were to consider moving coins as a taxable event... which is not) you would not pay as there is no gain nor loss.... You would pay for your posterior capital gains, in your case the $9000 per coin that results after substracting the initial cost ($1000) to the selling price ($10000).
Of course it is much more complex than that when you take into account FIFO/LIFO/PMP etc...
