  127. Recent Stocks Headlines You can make money trading Bitcoin – you can also lose it! Many people monitor Bitcoin’s price action through charts and either purchase BTC or buy BTC futures contracts which allow them to open long and short positions on Bitcoin. Trading such a volatile currency can be profitable, but is undeniably risky. Expand your choices for managing cryptocurrency risk with Bitcoin futures and options and discover opportunities in the growing interest for cryptocurrencies and the demand to manage Bitcoin exposure. Bitcoin’s price history is a clear reflection of the price volatility that the cryptocurrency market is widely recognised for. Its first significant price jump happened in 2010 when BTC appreciated from $0.0008 to $0.08 within a short span of time. It witnessed multiple rallies and crashes thereafter, month after month, and year after year.

    Stablecoins, crypto assets pegged to a non-crypto asset such the U.S. dollar, have gained considerable regulatory attention in recent years. A major concern with stablecoins is that a large number of stablecoin owners might try to redeem the underlying asset at once and the stablecoin issuer will not have the reserves necessary to meet demand. While House Financial Services Committee Chairman Patrick McHenry (R-NC) and Ranking Member Maxine Waters (D-CA) have stated their desire to work on bipartisan stablecoin legislation, to our knowledge, nothing has been made public as of this writing. “New York Attorney General Letitia James’ cryptocurrency legislation sets the standard for all U.S. states and territories on how to regulate the fledgling cryptocurrency industry,” said John Stark, former Founder and Chief of the Securities and Exchanges Commission’s (SEC) Office of Internet Enforcement. “This legislation brings much needed oversight to the industry and raises the bar, ensuring that investor protection remains paramount. I applaud Attorney General James and her team for this impactful legislation.”

  150. Public offerings may be made by issuers using existing digital assets, with the opportunity to create new ones through them, the law indicates. These digital currencies promise to maintain their value, which is generally pegged to a government currency like the dollar or euro, by relying on stable financial backing like bank reserves and short-term debt. They are exploding in popularity because they are a practical and cheap way to transact in cryptocurrency. Stablecoins have moved from virtual nonexistence to a more than $120 billion market in a few short years, with the bulk of that growth in the past 12 months. An ounce of gold doesn’t entitle you to exchange it for another valuable asset. Instead, the gold is valuable because the gold itself is valuable. Individuals are generally not worried about their gold becoming worthless because the market has established that gold has value for thousands of years. Similarly, Bitcoin’s value comes from the demand for Bitcoin and does not require any backing to maintain this value.

    Dogecoin is a digital token which gained popularity in 2021. Due to its uncapped maximum supply and comedic status, Dogecoin has seen price highs and has become available for trading on Coinbases, as stated by Cointelegraph. The program also accepts donations. According to a chart, the top 50 donors have donated $2,240 in various cryptocurrencies. Though those donations largely come from anonymous donors, the donor list includes certain Coinbase executives such as Associate General Counsel, Corporate Doug Sharp, and VP of Product Max Branzburg. Coinbase opened Base, an Ethereum layer-2 network, to the general public late last week in an effort to promote the creation of fresh decentralized applications within its ecosystem. Immediately after its launch, Base took off and quickly rose to the top five layer-2 networks by the quantity of bridged traffic.

  161. Past performance is not a guarantee or predictor of future performance. The value of digital assets can increase or decrease, and you could lose all or a substantial amount of your purchase price. When assessing a digital asset, it’s essential for you to do your own research and due diligence to make the best possible judgement, as any purchases shall be your sole responsibility. ” be pure coincidence that bitcoin’s halving cycles arrived just as narratives around crypto reached their frothy peaks, and the relationship is totally spurious,” Hume says. She goes on to also say that a major flaw in these scarcity-based analyses is that they all predict bitcoin's price will keep going up, which is impossible to know. The significance of Bitcoin halving is multifaceted. It represents Bitcoin’s approach to creating a synthetic form of inflation. Unlike traditional fiat currencies, where central banks can print more money, causing inflation, Bitcoin has a predetermined supply capped at 21 million. By halving the mining reward, Bitcoin makes sure its issuance rate decreases over time, slowing the influx of new coins into circulation.

    Before you hop on a nearby spaceship to a SafeMoon-supported crypto exchange, let’s whip out our metaphorical telescopes and zoom in on what SafeMoon is all about.  In order to pick up SafeMoon crypto, you used to need a Trust Wallet app with a little bit of Binance Coin (BNB) in it. Then you would head over to PancakeSwap and search around for SafeMoon. Once you’d found it, you’d set the slippage to between 11% and 12%, select the amount you wanted to purchase, press the swap button and then confirm the transaction. And along the way, it was almost a certainty that some pieces of the puzzle would fail on the first one to five times you tried them. At least, that was my experience. SafeMoon has integrated interoperability into its token, allowing users to bridge their tokens across the Binance Smart Chain, Ethereum, and Polygon. Which means that holders of the SafeMoon Token can now seamlessly transfer their tokens between these blockchain networks.
