Theoretically, you can buy it from someone who needs bitcoins. That is, you should search the web for those who will be interested in such a Christmas tree. I am sure there will be people wanting to conclude such a contract. Remember that many people are not asking for the most profitable bitcoin exchange rate for you. It is better to use a currency converter, which will help you get the most favorable terms of purchase. The rest is to create several topics with your proposal on different forums, and I'm sure someone will respond.
