Nvidia (NVDA) , a holding in Jim Cramer's Action Alerts PLUS Charitable Trust Portfolio, and AMD (AMD) are companies that make several types of technology; AMD makes processors for desktop and laptop computers, while Nvidia's products range from automotive use to cloud servers. Where the two most successfully intersect, though, are their graphics processing units. Even in the age of ASIC miners, a strong GPU has proven to be a competitive (and much more affordable) way to mine bitcoins.

One of those exchanges, Poloniex, argues pre-trading gives the crypto community the power to decide which coin they want to support. “We believe the responsible thing to do in this case is remain neutral and allow the community to decide which chain to support, and we want to empower the community to demonstrate their support through trading activity,” Poloniex said in a press release.


As used in bitcoin, blockchain is a public ledger of all bitcoin transactions that have ever been made. When a transaction is completed, it is recorded on a new "block." When the block is full of such transactions, it is added to the end of the "chain" in sequential order, and a new block is created. Full blocks are a part of the blockchain's permanent database. Each node -- a computer connected to the bitcoin network for the purpose of verifying transactions -- automatically gets a downloaded copy of the blockchain upon joining the network. The blockchain records information like the time and amount of each transaction, but it does not store any personal information on the parties involved.

With more mainstream interest in Cryptocurrency multiplying by the day it is important that Phore introduces a mobile wallet for the iPhone an iPad, which facilitates use by the large amount of Phore holders on IOS, bringing it to parity with Android. The process for creating and distributing this through the Apple Store is more complicated than Google Play, which is why the release has been scheduled to take longer.

Once you have a Bitcoin wallet, you use a traditional payment method such as credit card, bank transfer (ACH), or debit card to buy Bitcoins on a Bitcoin exchange (example: Coinbase). The Bitcoins are then transferred to your wallet. The availability of the above payment methods is subject to the area of jurisdiction and exchange chosen. Here is a screenshot of the Bitcoin interface showing how to buy and sell not just Bitcoin but also Bitcoin Cash, Ethereum and Litecoin​, which are other popular virtual currencies. As you see, it's as straightforward as clicking on the "Buy" tab if you want to buy, and "Sell" tab if you want to sell. You select which currency you are buying/selling and which payment method (your bank account or credit card) you want to use.
Finally, as everyone who held Bitcoins before the split received an equal amount of Bitcoin Cash tokens, some people voiced their concerns that the split was nothing but a money-making scheme. In fact, the hard fork did create a situation similar to a double-spending problem, as it made conducting two transactions from a single wallet using the same set of keys possible.
If this process sounds a bit cumbersome, it is. This means bitcoin is much less liquid than traditional equities, creating more volatility and wild swings. For instance, in the past month alone, the value of one bitcoin fell from prices over $2,500 to under $2,000 before regaining all-time highs over $3,400. Those are incredibly volatile swings within one month -- something virtually unheard of with any other type of currency!
