I just took another look at this. I haven't verified the existence of that order, or whether or not it was actually filled - I'll just take your word for it. But if it was filled, before it took off, it's not a lot of money. Taking the April 20th price (which is not dissimilar to the early December price) 450m XRP would have cost a little over $13m. If this is part of your proof of a massive conspiracy by transnational banks trying to kill off the decentralized crypto revolution, it's not a very convincing number!
