Hi, I live in the US and bought 2 BTC last week at Coinbase on Mar 15 and haven’t seen the Bitcoins appear in my wallet yet (today is 20th Mar). Even after providing personal details and being promised to buy/sell instantly I don’t seen that happening any time soon. And to top it all they charged me 1.49% in fees (can provide screenshots of the transactions).
There are many reasons why the digital currencies are gaining popularity and momentum around the world. They have a finite supply that has been identified and source codes outline the exact number that can exist. Users of this currency benefit differently from users of traditional currency. For example, governments cannot intervene and banks cannot freeze your account. Since there is a limit on the amount, cryptocurrencies in that sense, are finite commodities, more like metals than a currency, and with time their value could go up. They are attractive to people who worry about direct control of national banks and governments. Privacy and anonymity are key to the ownership of these coins which many people appreciate. It is more and more difficult to identify accounts of users. Generally, transactions are cheaper than the traditional way using banks. Overall cryptocurrencies can change the financial world, and for the moment it is all still being worked on. Users of these coins still do need to remain aware of their limitations and volatility for the time being and foreseeable future. Their price flow is defined for the most part by market demand and thanks to the complicated code involved cryptocurrencies are impossible to counterfeit. They do make for a rewarding albeit uncertain investment endeavour. The long term results are still unknown but cryptocurrencies are only growing in popularity and for the immediate future they are here to stay and will most probably thrive.
The currencies modeled after bitcoin are collectively called altcoins and have tried to present themselves as modified or improved versions of bitcoin. While some of these currencies are easier to mine than bitcoin is, there are tradeoffs, including greater risk brought on by lesser liquidity, acceptance and value retention. (For more, see our guides on bitcoin mining and bitcoin regulation.)

"Too much confidence and greed may damage your account" At previous analysis, I draw this bullish flag, but not following it, and with extra confidence I take short position. Lucky for me, my extra confidence use no leverage and already hit stoploss. We know that not everyone agree with bearish at bitcoin, so we draw this bullish flag pattern with projection at...

Paul Krugman, Nobel Memorial Prize in Economic Sciences winner does not like bitcoin, has repeated numerous times that it is a bubble that will not last[92] and links it to Tulip mania.[93] American business magnate Warren Buffett thinks that cryptocurrency will come to a bad ending.[94] In October 2017, BlackRock CEO Laurence D. Fink called bitcoin an 'index of money laundering'.[95] "Bitcoin just shows you how much demand for money laundering there is in the world," he said.
In other words, these are the coins that we think make the most valid investments (in general, not at a given moment) and are worth exploring for new coin users (not simply the coins with the highest market cap, value, or most relevance alone). With that said, any “best of” list is bound to have a bias, and this is true for this list as well. Feel free to make up your mind.

TIP: The top coins by market cap are usually the best bets. Most of the top coins today were toward the top of the list back in 2015. There are a few coins high on the list today that you should be wary of, for example, Bitconnect. There are a few new ones, like the Bitcoin forks, Bitcoin Cash and Bitcoin Gold, that are new to the list. Meanwhile, there are a few that didn’t stand up to the test of time, like Peercoin. As a rule of thumb, historically speaking, the higher the coin is on the list, the more solid it is an investment over time.

A cryptocurrency is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. Many cryptocurrencies are decentralized systems based on blockchain technology, a distributed ledger enforced by a disparate network of computers. A defining feature of a cryptocurrency, and arguably its biggest allure, is its organic nature; it is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.
Bitcoin continues to lead the pack of cryptocurrencies, in terms of market capitalization, user base and popularity. Nevertheless, virtual currencies such as ethereum and ripple, which are being used more for enterprise solutions, are becoming popular, while some altcoins are being endorsed for superior or advanced features vis-à-vis bitcoins. Going by the current trend, cryptocurrencies are here to stay but how many of them will emerge as leaders amid the growing competition within the space will only be revealed with time.
Ethereum: Is probably the third most important coin [here in 2018, I’d argue that it is the second most important after Bitcoin]. Ethereum doesn’t have the longevity at the top like Litecoin, but it has some unique features and a market cap that make it a real contender. Most ICOs (Initial Coin Offerings) use Ethereum. It has a less intimidating cost that Bitcoin and has the second highest market cap. On that note, Ethereum classic is also notable. Ethereum is a spin-off (aka “hard fork”) from what isn’t today called Ethereum classic (like how our next up coin, Bitcoin cash, is a spin-off of Bitcoin.) NOTE: Ethereum is a fork of another relevant coin called Ethereum Classic.

Bitcoin Gold (BTG) is the second fork from Bitcoin (i.e. the second version to stem from Bitcoin’s source code). It retains Bitcoin’s transaction history, meaning that if you owned Bitcoin before the fork, you now own the equal amount of Bitcoin Gold. This cryptocurrency aims to introduce an alternative mining algorithm that is less susceptible to ASIC-based optimization, therefore allowing users to earn more with their computer cycles.
Peercoin: Like Nxt, Peercoin (abbreviated PPC) uses a proof-of-stake system; in fact, it was the first proof-of-stake coin. It’s worth about $0.40 on the USD and has a market cap of almost ten million. This coin has everything going for it and might be a smart bet as far as cryptocurrency goes. As an bonus to the confidence and quality of the coin, Peercoin was developed by Sunny King. Sunny King is, or might be, the person who created Bitcoin or another coin, or maybe Bruce Wayne or Clark Kent. It’s hard to tell as the culture of cryptocurrency puts importance on peer-to-peer, code, and coin over developers. Still, he is important, and like-it-or-not little things like this could be the deciding factor in whether a coin sinks or swims in the new market. Peercoin has a story like Nxt and Namecoin where they are long-running coins.

Litecoin, launched in 2011, was among the initial cryptocurrencies following bitcoin and has often been referred to as “silver to bitcoin’s gold.” It was created by Charlie Lee, an MIT graduate and former Google engineer. Litecoin is based on an open source global payment network that is not controlled by any central authority and uses "scrypt" as a proof of work, which can be decoded with the help of CPUs of consumer grade. Although Litecoin is like bitcoin in many ways, it has a faster block generation rate and hence offers a faster transaction confirmation. Other than developers, there are a growing number of merchants who accept Litecoin. As of February 9, 2019, Litecoin had a market cap of $2.63 billion and a per token value of $43.41.

Schließlich liegt jeder digitalen Währung eine eigene ganz besondere Funktionsweise zu Grunde, welches im Laufe der Zeit auch über deren Erfolg und Wertsteigerung entscheiden dürfte. Außerdem informieren sich kluge Trader ohnehin immer über die zu handelnden Produkte, um dann vor keine Überraschungen gestellt zu werden, wenn es um den konkreten Handel geht.
An increase in cryptocurrency mining increased the demand of graphics cards (GPU) in 2017.[37] Popular favorites of cryptocurrency miners such as Nvidia's GTX 1060 and GTX 1070 graphics cards, as well as AMD's RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock.[38] A GTX 1070 Ti which was released at a price of $450 sold for as much as $1100. Another popular card GTX 1060's 6 GB model was released at an MSRP of $250, sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU's as soon as they are available.[39]
