If you decided to continuing with compass mining, I think the selected 2nd option is the least risky. Option 1 is very unfair in my point of veiw, 3rd and 5th option is high risk because of CBP (and in this case of a large transport, it is almost certain to be booked => extra costs for alternative shipping, storage, duty, etc). The 4th option is THE BEST....but just only in case if you have more than 100k BTC already ;)
