Since all of the virtual currencies remain a speculative asset, investors should avoid buying them for their retirement portfolios, says Jason Spatafora, co-founder of and a Miami-based trader and investor. Cryptocurrencies made up less than 2 percent of his portfolio a few months ago, but he is no longer trading them because of the extreme volatility.
Cryptocurrencies have been compared to Ponzi schemes, pyramid schemes[77] and economic bubbles,[78] such as housing market bubbles.[79] Howard Marks of Oaktree Capital Management stated in 2017 that digital currencies were "nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it", and compared them to the tulip mania (1637), South Sea Bubble (1720), and dot-com bubble (1999).[80]

Welcome to Bitcoin' and triangle movements, one day looking so bullish and few days later looking so bearish and back again. This pingpong behavior has been going on for a few months now. Bears get out of hiding when the downside gets tested and the bulls show up when the upside gets tested. In the meantime it's just the exchanges that earn real money, even though ...
Monero is a privacy coin and the preferred coin in darknet markets (which is likely why Coinbase won’t be adding it any time soon). It has solid transaction schematics that involves ring signatures and stealth addresses created on an ad hoc basis to keep transactions private. Monero also runs on a proof of work verification standard similar to Bitcoin. PoW means there will always be a value behind XMR, even if only the cost of energy. Finally, Monero has a strong base of community support because it was founded on principles of privacy and decentralization. These values are central to the original cryptocurrency concept. This is why I think it is a good long term investment right now.
In order to send or receive bitcoins, all you need to have is a bitcoin address and internet access. You only need to be online long enough for the transaction to process. Similarly to traditional bank accounts, you can receive bitcoins to your bitcoin address even if you’re offline. When you want to ‘’collect’’ your coins however, you’ll have to find an internet connection.
Decentralized exchanges have been around for some time. As far back as 2015, BitShares DEX, Coinffeine, and OpenLedger all claimed the coveted world’s first decentralized exchange title. EtherDelta, 0x, Kyber Network, AirSwap, and a number of others have joined the fray since. While they’ve generally offered better security, they’re far from perfect.
While looking for a reliable online exchange might be a complicated task, trusting a platform with extensive coverage and positive reputation among its users might save your time. CEX.IO is the Bitcoin trading platform that combines the crucial features: enhanced security, variety of options and high market liquidity.

Support levels, in a sense, are the mirror image of resistance levels. They look like a “floor” Bitcoin’s price doesn’t seem to go below when the price drops . A support level will be accompanied by a lot of buy orders set at the level’s price. The high demand of a buyer at the support level cushions the downtrend. Historically, the more frequently the price has been unable to move beyond the support or resistance levels, the stronger these levels are considered.

Many Bitcoin enthusiasts argue that altcoins are completely unnecessary and will not succeed because they cannot rival the infrastructure Bitcoin boasts. However, altcoins serve an important role. Decentralization is one of Bitcoin’s most prominent goals, and altcoins further decentralize the cryptocurrency community. Moreover, altcoins allow developers to experiment with unique features. While it is true that Bitcoin can copy these features if the developers or community desires, fully-functioning altcoins are much better “cryptocurrency laboratories” than Bitcoin’s testnet. Finally, Altcoins give Bitcoin healthy competition. Altcoins give cryptocurrency users alternative options and forces Bitcoin’s developers to remain active and continue innovating. If users do not feel that Bitcoin satisfies their digital desires, they can adopt an altcoin. If enough users left Bitcoin for a particular altcoin, the Bitcoin developers would have to adopt the features the community desired or risk losing its place as the preeminent cryptocurrency.

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.
