Other than moving to another country it would be wise to move your winnings to a p2p exchange platform with that you would both avoid the tax that would be charged as well as the cost of starting a new life in a different country.
Yes, it's a good solution to implement for those who want to move from one country to another,
but can a p2p exchange platform be very safe to store assets that we already have?
Even if you use P2P exchange and you are withdrawing huge amounts IRS will be notified and you might get a letter asking for the source of income. The best option is to travel to a country with lower taxation if you are planning to withdraw huge amounts, start a small business and then send them back home, if not withdraw small amounts without raising suspicion by the IRS.
