CAPITAL GAINS !!!!!!!!!!!!!!
If a dude is holding 350 bitcoins and makes $350,000 ......
Some such dudes are going to have to give $100,000 of it to the government "just because" ....
Maybe the correct question is, how many people are applying for citizenship in Germany right now?
I'm surprised nobody has qualified the "cash out" option with a date - does it really makes sense to cash out for a bunch of fiat right before the end of the year, when you would have to claim it as income only a few months later? Why not wait until January at least so that you have over a year before you have to claim anything for taxes?
If you want to put it as fiat at least maybe you could invest the portion needed to pay taxes for the year interim and lessen the impact. But maybe that's just me...
In the US I believe you might need to pay quarterly estimated tax on capital gains. If you don't you could be hit with a penalty when you go to file your taxes for that year.
