Groestlcoin is a privacy centric Peer-to-Peer (P2P) cryptocurrency that was launched in 2014. It was developed to be an ASIC resistant version of Bitcoin. They were able to achieve a number of important firsts including being the first coin to implement Segregated Witness and it was also the first to perform a Lightning Network transaction on the mainnet Groestlcoin is a PoW cryptocurrency and it is unique in that it is one of the few coins that make use of the Grøstl-512 mining algorithm. This is less complex than Bitcoin's algorithm which means that it is still possible to mine this coin with your GPU. There is a maximum supply of 105 million GRS and so far, just over 72 million are in circulation. The coin also has a much shorter block time of only 1 minutes with a large total supply and weekly subsidy halvings. This all contributes to cheap and fast transaction times. You can send 10,000 GRS and the cost will be far less than a penny. The developers behind the Groestlcoin project are anonymous but have a well-established reputation in the community. This team has been regularly updating the protocol as evidenced by the extremely active GitHub repositories. The project has some of the most active repositories in the cryptocurrency market currently. There is also a pretty active community behind Groestlcoin which could be an invaluable factor when it comes to long term adoption of the coin. GRS has had quite a rocky ride since its initial listings on exchanges back in 2014. It reached an all time high in the 2018 bull run of $1.64. However, since the bear market has begun to bite it has followed the rest of the market lower. GRS is currently listed on a number of exchanges although the bulk of the volume is on UpBit and Binance. There is strong volume and liquidity in the token on these exchanges but the tokens remain quite volatile.
On 21 November 2017, the Tether cryptocurrency announced they were hacked, losing $31 million in USDT from their primary wallet. The company has 'tagged' the stolen currency, hoping to 'lock' them in the hacker's wallet (making them unspendable). Tether indicates that it is building a new core for its primary wallet in response to the attack in order to prevent the stolen coins from being used.
Hey there! I am Sudhir Khatwani, an IT bank professional turned into a cryptocurrency and blockchain proponent from Pune, India. Cryptocurrencies and blockchain will change human life in inconceivable ways and I am here to empower people to understand this new ecosystem so that they can use it for their benefit. You will find me reading about cryptonomics and eating if I am not doing anything else.
The semi-anonymous nature of cryptocurrency transactions makes them well-suited for a host of nefarious activities, such as money laundering and tax evasion. However, cryptocurrency advocates often value the anonymity highly. Some cryptocurrencies are more private than others. Bitcoin, for instance, is a relatively poor choice for conducting illegal business online, and forensic analysis of bitcoin transactions has led authorities to arrest and prosecute criminals. More privacy-oriented coins do exist, such as Dash, ZCash, or Monero, which are far more difficult to trace.
A lot of people have made fortunes by mining Bitcoins. Back in the days, you could make substantial profits from mining using just your computer, or even a powerful enough laptop. These days, Bitcoin mining can only become profitable if you’re willing to invest in an industrial-grade mining hardware. This, of course, incurs huge electricity bills on top of the price of all the necessary equipment.
Darkcoin (Dash): Darkcoin, known as Dash as of March 25, 2015 (dash=digital cash), but previously known as XCoin, has unique functionality. XCoin was developed by Evan Duffield who wanted to improve on Bitcoin but didn’t have the pull to do so. Thus, he developed his own coin. It takes less power to mine Dash than most coins. Using less energy to mine is important because mining coins is one of the most wasteful processes you can imagine. The wasteful mining process is key to security and stability of all coins that use a “proof-of-work” system. It prevents people from mining too fast. However, environmentally, it’s a nightmare. In 2015 we had said, “People know what a Darkcoin is. Hopefully, this familiarity rolls over to Dash” (today few remember XCoin and Darkcoin, and Dash is a well-known crypto). Back in 2015, Dash was one of the higher valued coins. Today that is still true, and Dash has performed almost as well competitors like Ethereum.
If a coin isn’t in the top 50 – 100 on CoinMarketCap.com, it is not a safe and sound investment for someone who wants to see a return as a rule of thumb. Once in a while I invest in coins in the 100 – 200 by market cap range, but this is after research and is very case specific. Further down the list we go, the less demand essentially. We want to be in coins that have enough demand to sell them later (hopefully at a profit)!
“I tried an automatic trading software, but it didn’t seem to be good for me, because I wanted to be involved in the process, since I am retired and I have a lot of free time. Tried trading with a personal broker and got very interested, after a few educational sessions with her, I managed to start trading smart and increase my investment up to 235% in just a matter of month. It’s about 120-160 Euros a day now. “
The validity of each cryptocurrency's coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way". For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
