You will have to pay taxes for such a big amount. Other than that it is fine.
I don't even know where to begin searching for tax information. All the coins I have, I mined. In any case, my main concern was a hold up with the banks.
Perhaps this is the wrong forum for this type of question and I should speak directly with my bank first, as well as an accountant. It's my first time converting coins to fiat so it's a bit new to me.
