The whole crypto world discusses how Ethereum will switch from Proof of Work to Proof of Stake now. This change can significantly affect the cryptocurrency market. What are the positive and negative sides of PoW and PoS?submitted by CoinjoyAssistant to ethtrader [link] [comments]
Cryptocurrencies can be divided into two types: those that can be mined (Bitcoin, Litecoin, Monero) and pre-mined ones (Ripple, Stellar, Cardano, EOS, NEO).
What is the big difference?Although they differ in the method of generation, the basis of both types of crypto is the same: verification. Every transaction processed by the network must be verified by someone to ensure that virtual money has not been spent twice. Here we are talking about the difference in the verification process. Transaction groups are combined into a block; after verification, the block joins other previously confirmed blocks, and create a chain of transactions, or blockchain.
PoW: Mined CryptoMining is a process in which individuals, groups, or companies solve complex mathematical equations to verify transaction blocks using powerful computers. These math problems are part of the encryption process that protects transactions from cybercriminals and third party access.
The first who solves the problem and signs a block of transactions receives a reward. The miner, who confirmed the block of transactions e.g. in the Bitcoin network, receives a reward in BTC.
Disadvantages of Mined Crypto
PoS: Non-Mined CryptoAt the other end of the spectrum are pre-mined cryptocurrencies such as Ripple (XRP), Stellar, Cardano, EOS, and NEO.
In the PoS model, super-powered computers are not needed, and participants do not compete for the right to sign the next block. Thus, the costs of this approach are significantly lower. Transaction verification is carried out by cryptocurrency owners. The more cryptocurrencies you have, the longer you own it, the higher the probability that you will be selected to check the transaction block.
Certain mechanisms are built into the system that prevents the dominance of large cryptocurrency holders over the verification process. There are many random ways to select owners who get the right to sign a transaction block. This ensures that small holders have a chance to participate in the process.
Disadvantages of Non-Mined CryptoDespite the fact that the costs of the Proof-of-Stake method are lower, PoS has its drawbacks.
Which method is better?Both methods have their pros and cons. Nevertheless, sooner or later, some of the largest mined currencies (e.g. BTC) will reach their token limit. At this point, they will have to switch to Proof-of-Stake. Since it significantly reduces power consumption and doesn't require powerful computers, gradually all crypto including BTC will switch to a non-mined model just like Ether did.

NewsSquare Quietly Launches Program For CBD Cannabis Company Credit Card Processing | May 22 2019
Companies that sell cannabis products—even those consisting of CBD derived from hemp, which was legalized in the U.S. through the Farm Bill late last year—are continuing to have trouble accessing basic financial services that are available to businesses in other sectors. That includes being able to maintain bank accounts and process their customers' credit cards. “Square is currently conducting an invite-only beta for some CBD products,” a spokesperson for the company said in an email. When asked about the reasons for the launching the new program, which comes after years of refusing to work with CBD companies, the spokesperson said that the company closely watches evolving public policies and strives to create new opportunities for clients.
Square Spends $20 to Acquire Each New Cash App User | May 16, 2019
Square's (NYSE: SQ) Cash App has grown to become a meaningful contributor to the company's top-line growth. The peer-to-peer payments app turned financial multitool is the No. 1 driver of its subscription and services segment, management said at the J.P. Morgan Global Technology, Media and Communications Conference. During that conference, CFO Amrita Ahuja noted the company's per-customer acquisition cost for Cash App is about $20. That's actually quite low relative to other financial services, and even compared to other apps.
Square’s AI Platform Could Transform SQ Stock | May 13, 2019
Eloquent Labs is the developer of Elle, which can converse intelligently with a customer through a conventional online-chat platform without any human input from the service provider.

Square's Bitcoin Platform Remains Surprisingly Profitable | May 7, 2019
Square's bitcoin revenue accounted for 6.8% of its net revenue during the first quarter, compared to 5.1% in the prior year quarter. However, Square's bitcoin profits only accounted for about 0.2% of its gross profit during the quarter, versus less than 0.1% a year earlier. Square's bitcoin business won't move the needle anytime soon, but its top and bottom line growth is impressive, especially since bitcoin shed roughly 40% of its value over the past 12 months. If bitcoin's price rises again and it attracts more buyers, Square's bitcoin revenue and gross profits could surge much higher.
Instead of viewing Square's bitcoin platform as a separate business, investors should see it as part of the company's long-term plan to lock users into its Cash App. Cash is one of the top peer-to-peer payment apps in the U.S. alongside PayPal's (NASDAQ: PYPL) Venmo and the bank-based Zelle, and it's still growing rapidly. Last quarter Square stated that its Cash App payment volume rose nearly 2.5 times annually. For comparison, PayPal stated that Venmo's payment volume rose 73% annually in its most recent quarter.

Why Square Is Hiring Cryptocurrency Experts | April 3, 2019

Square operates a cryptocurrency exchange that allows users of its Cash App to buy and sell Bitcoin.

Square is already making a small profit from its Bitcoin business even though the overall business is still seeing losses.
