No Transaction Costs: All bitcoin transactions are digitally recorded on public networks without any involvement from banks or clearing agencies. Hence, there are usually no transaction costs involved in bitcoin, even for global transfers. Brokers pass these benefits to the clients by not imposing any deposit or withdrawal fee for bitcoin transactions. This improves trade profits.
The list goes on with Stellar, Monero, Neo, Ethereum Classic, Tezos, Maker, and BAT all getting good news and positive developments over the past couple of months but not seeing any beneficial price action. It seems that all those that have been burnt during the first half of the year are out of the market and are too afraid to get back in. Cryptocurrency levels now are back to mid-2017 prices and it will take a lot more than positive news to see them surging again.

In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day there can only be one winning answer. When multiple simultaneous answers are presented that are equal to or less than the target number, the Bitcoin network will decide by a simple majority--51%--which miner to honour. Typically, it is the miner who has done the most work, i.e. verifies the most transactions. The losing block then becomes an "orphan block." 
Most cryptocurrencies are designed to gradually decrease production of that currency, placing a cap on the total amount of that currency that will ever be in circulation.[25] Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement.[1] This difficulty is derived from leveraging cryptographic technologies.
The Darkcoin devs created a tool called DarkSend. DarkSend is an implementation of coinjoin (an anonymity feature originally implemented in Bitcoin[5]) which utilizes the Darkcoin network to organize the coinjoins. If DarkSend becomes open source and is useful, it will be ported to Bitcoin with a few small modifications. These changes won't be a hardfork, they will likely involve the masternodes being paid by those they are coinjoining for rather than the block reward, which is already possible and implemented for Bitcoin. [6]Currently one must hold 1000DRK to become a DarkSend masternodes. Masternodes are paid 10% of the block reward.[7] This is a flawed reward scheme because while purchasing 1000DRK is trustlessly verifiable, a user running a DarkSend masternode isn't trustlessly verifiable. It is also costs bandwidth to run a masternode, therefore there is an incentive to buy 1000DRK and get a chance at the 10% block reward masternodes are being paid, but not actually act as a masternode. For this reason, DarkSend would work better if the masternodes were paid by those they were helping coinjoin, or if there wasn't a masternode at all and everyone collaborated in a decentralized fashion. The better implementation not vulnerable to tragedy of the commons is compatible with Bitcoin, therefore, the Darksend protocol serves no purpose.
A market order in this case would submit a buy order for XBT at the price of the lowest available sell order. Using the orderbook above, a market order for 0.5 XBT would purchase 0.5 XBT at $384.07 per XBT. If selling bitcoins, a market order would sell bitcoins for the highest available price based on the current buy orderbook—in this case $382.5.
In addition to lining the pockets of miners, mining serves a second and vital purpose: It is the only way to release new cryptocurrency into circulation. In other words, miners are basically "minting" currency. For example, as of the time of writing this piece, there were about 17 million Bitcoin in circulation. Aside from the coins minted via the genesis block (the very first block created by Bitcoin founder Satoshi Nakamoto himself), every single one of those Bitcoin came into being because of miners. In the absence of miners, Bitcoin would still exist and be usable, but there would never be any additional Bitcoin. There will come a time when Bitcoin mining ends; per the Bitcoin Protocol, the number of Bitcoin will be capped at 21 million.

According to BitPay, a Bitcoin Payment Service Provider, as of November 2013 there are over 14,000 merchants currently accepting bitcoins. Two years ago this number stood at few hundred. The number of transactions facilitated by Bitpay increased tenfold in 2014 and crossed the 50,000 mark in November. The payment processor said that 6,296 bitcoin transactions occurred on Black Friday last year, up from only 99 transactions the year prior.
2018 however seems to have been the complete opposite with bears smashing the markets despite positive news coming from several directions. This week has been a prime example with a number of altcoins getting some good news but seeing no positive effects on prices. Those that do get a pump usually get dumped the following day or sooner anyway, the momentum is just not lasting.
Bitcoins are mined with powerful computer hardware and software. A maximum of 21 million Bitcoin will be available, after which no further bitcoins will be produced. The algorithm which governs the production of Bitcoin limits the quantity that will be produced, and the rate at which they will be produced. It is a finite commodity – there is a fixed amount, and that ensures that greater demand will always prop up the price. In this way, it is similar to other finite commodities such as crude oil, silver, or gold.
