Forget about 69 Billion Japanese yen and $40 million forked coin BCH.
Mt Gox will pay 142000 Bitcoins to creditors around $4.3 billion.
As far as I know, Mt.Gox will not pay everything at once, but in several tranches - and in addition, everyone got the option to choose whether they want to be paid in BTC/BCH or to their bank accounts. I believe that a part of people will prefer to accept payments to their bank accounts, which means that a good part of BTC will be sold by the bankruptcy trustee, and I hope that he has at least some business sense and will do it using OTC.
Some just want to take advantage of the possibility that this will happen, but for me personally it is overblown and according to what I have already written, it should not have too much impact on the price of BTC. Of course, I'm not saying that people won't panic, as with any similar news - but weak hands will always be welcome to fill the bags of those who are just waiting for such opportunities.
