If you held the virtual currency for one year or less before selling or exchanging the virtual currency, then you will have a short-term capital gain or loss. If you transfer property that is not a capital asset in exchange for virtual currency, you will recognize an ordinary gain or loss. Looking for a reliable online exchange might be a complicated task.

If you control nodes that peer with the exchange, you might be able to change the txid for your withdrawal using transaction malleability. If a transaction malleability attack occurs, and the txid changes, then the transaction will eventually be added to the blockchain, but under an unexpected txid. It is thought that this attack was used against some Bitcoin exchanges, including Mt Gox. It's possible that only a small percentage of stolen coins from Mt Gox were taken using this attack, or even none at all. Maybe you don't even mind a world where eveyone is continuously "doxxed" and bombared with perfectly targetted ads a là Minority Report.

Bryan Armour, director of passive strategies research for North America at Morningstar, said a spot bitcoin ETF could be a more cost-effective way for investors to trade.

This week’s newsletter links to a website that tracks miner support for taproot activation, announces a new organization funding Bitcoin research and development, and includes our regular sections with popular questions and answers from the Bitcoin Stack Exchange, announcements of releases and release candidates, and notable changes to popular Bitcoin infrastructure software. This week’s newsletter links to a blog post about how a small change to thscriptpt language after taproot activation could enable increased contract flexibility and includes our regular sections with notable changes to popular Bitcoin infrastructure projects. This padding changes the transaction hash, just as adding trailing whitespace to a source code file would change the file hash. However, Bob can make some changes that don't change the transaction semantics, but do change the computed txid. You can use the Bitcoin Optech dashboard to see these stats as historical trends from the entire history of Bitcoin, and also from new blocks as they get confirmed.

Usually it takes less than a minute from the time a transaction is created until it fully propagates to the rest of the network. If 90% of the blocks in a given time frame are not Taproot-supporting, then that means miners don’t support the upgrade and activation fails. Reaction to the proposal was mixed (pro: 1, 2; con: 1, 2), but this week one hardware wallet manufacturer stated their intent to implement support for the protocol and requested additional review of the proposal. There was no reason this should’ve happened since we bought it through the app especially for longer than a week . Security, for example, is far from perfect: there have been more than 40 known thefts and seizures of bitcoins, several incurring losses of more than $1 million apiece. The original Bitcoin implementation was underspecified with respect to how txids were actually calculated (more on this in a moment). Transaction malleability is already more or less fixed in Bitcoin, but Segwit will improve the situation further with the introduction of a new type of txid, the wtxid (i.e. "witness" txid).
