Elsewhere, here is the story of block.one, which "has raised about $700 million and counting" by selling EOS tokens that it says "do not have any rights, uses, purpose, attributes, functionalities or features." Block.one is using the money to build "a new blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications," as its white paper explains, and the white paper also includes a disclaimer in bold capitals:

Almost every crypto-list today starts off with the king – Bitcoin! Satoshi Nakamoto created Bitcoin a long time ago, and it was the first cryptocurrency to step blinking into the bright light of the world! Bitcoin has surpassed all expecatations and continues to grow in value and popularity – despite recent setbacks and a lot of FUD from trolls and haters (read: traditional banks) online.  Will Bitcoin continue to increase in value in 2018? Recent trends say: Yes! In my opinion, any cryptocurrency portfolio should hold some Bitcoin.
OmiseGO (OMG) is a public financial technology that’s based on Ethereum. The concept of OMG is to enable peer-to-peer value exchange and payment service in real time across not only decentralized currencies but fiat money as well. OmiseGO allows anyone on its network to process financial transactions (payrolls, B2B, remittances, payments, etc.) in a much more inexpensive and decentralized manner.

If a Fund that writes an option wishes to terminate the Fund’s obligation, the Fund may effect a “closing purchase transaction.” The Fund accomplishes this by buying an option of the same series as the option previously written by the Fund. The effect of the purchase is that the writer’s position will be canceled by the OCC. However, a writer may not effect a closing purchase transaction after the writer has been notified of the exercise of an option. Likewise, a Fund which is the holder of an option may liquidate its position by effecting a “closing sale transaction.” The Fund accomplishes this by selling an option of the same series as the option previously purchased by the Fund. There is no guarantee that either a closing purchase or a closing sale transaction can be effected. If any call or put option is not exercised or sold, the option will become worthless on its expiration date. A Fund will realize a gain (or a loss) on a closing purchase transaction with respect to a call or a put option previously written by the Fund if the premium, plus commission costs, paid by the Fund to purchase the call or put option to close the transaction is less (or greater) than the premium, less commission costs, received by the Fund on the sale of the call or the put option. The Fund also will realize a gain if a call or put option which the Fund has written lapses unexercised, because the Fund would retain the premium.

  (c) A “Disinterested Trustee” is one (i) who is not an Interested Person of the Trust (including anyone, as such Disinterested Trustees, who has been exempted from being an Interested Person by any rule, regulation or order of the Commission), and (ii) against whom none of such actions, suits or other proceedings or another action, suit or other proceeding on the same or similar grounds is then or has been pending;
Yields on U.S. government securities depend on a variety of factors, including the general conditions of the money and bond markets, the size of a particular offering, and the maturity of the obligation. Debt securities with longer maturities tend to produce higher yields and are generally subject to potentially greater capital appreciation and depreciation than obligations with shorter maturities and lower yields. The market value of U.S. government securities generally varies inversely with changes in market interest rates. An increase in interest rates, therefore, would generally reduce the market value of a Fund’s portfolio investments in U.S. government securities, while a decline in interest rates would generally increase the market value of a Fund’s portfolio investments in these securities.
  shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.
Index options are subject to substantial risks, including the risk of imperfect correlation between the option price and the value of the underlying assets composing the index selected, the possibility of an illiquid market for the option or the inability of counterparties to perform. Because the value of an index option depends upon movements in the level of the index rather than the
Anyone interested in buying bitcoins needs to deposit funds in U.S. dollars, euros, or another currency supported by the exchange. The popular methods of transferring money to the currency exchanges are through bank wire transfers, credit cards, or liberty reserves. One of the pre-requisites here is to have a digital wallet to hold bitcoins. Bitcoins bought can be stored in a digital wallet, device, or paper wallet, depending on the buyer’s preference. For sellers, the fait currency for which the Bitcoins have been sold needs to be withdrawn from the exchange and sent to a bank. One issue that can arise is if the exchange has liquidity concerns at a particular point in time; such situations can delay withdrawal and transfer of funds into a bank account.

I’m a nomad from The States, currently residing in Indonesia. Can you suggest the best global service for wallets/exchanges? In The States it’s Coinbase but its supported countries are extremely limited for my needs limited. I need something I can access in basically any country without issue. I know there are a options out there, but I wanted to get you opinion of how other travelers have gotten past this.
An increase in cryptocurrency mining increased the demand of graphics cards (GPU) in 2017.[49] Popular favorites of cryptocurrency miners such as Nvidia’s GTX 1060 and GTX 1070 graphics cards, as well as AMD’s RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock.[50] A GTX 1070 Ti which was released at a price of $450 sold for as much as $1100. Another popular card GTX 1060's 6 GB model was released at an MSRP of $250, sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU's as soon as they are available.[51]

Changes in the laws of the United States and/or the Cayman Islands, under which the Parent Funds and the Subsidiaries are organized, respectively, could result in the inability of a Parent Fund and/or its respective Subsidiary to operate as described in this SAI and could negatively affect a Parent Fund and its shareholders. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiaries. If Cayman Islands law changes such that a Subsidiary must pay Cayman Islands taxes, Parent Fund shareholders would likely suffer decreased investment returns. See “Taxation” below for more information.

Since you bought 68.4246 BTC, you want to short 68 BTC and lock in the USD value. You will have 0.4246 BTC left over, which will give you a slightly long bias. You can either fix this by only buying 68 BTC in step 1 or by giving yourself more short exposure by shorting 69 BTC. Remember that CryptoFacilities contracts are inverse (which allow locking in USD) and are denominated in BTC
