Ethereum is an open source, peer-to-peer, community driven decentralized cryptocurrency that allow people to store and invest their wealth in a non-government controlled currency, and even earn a substantial interest on investment. This means anyone holding Ethereum Coin in their wallet will receive interest on their balance in return for helping maintain security of the network.

Ethereum: Had 40x growth rate over the last two years. Allows to build fully-functional applications on blockchain without middlemen. Extremely promising currency, solid team (take a look at what Vitalik Buterin is doing right now). #2 crypto right now — but still 1/10 of the Bitcoin value.

Monero: Anonymous / private Bitcoin. Now, you may think, “What are you talking about, the BTC is anonymous already?” — which is a very unfortunate albeit popular misconception. All BTC transactions can be seen by the public. For example, by giving out your wallet address to someone, the person is able to see all the payments you’ve received and sent. The black market (drug dealers and weapon manufacturers) created a solution for this: basically a software that mixes your coins with other coins. Nevertheless, the software needs to be trusted and may not work correctly.

Factom: A blockchain-based system that’s optimized to store millions of realtime records with a single hash. Useful for all kinds of business apps. Runs on top of Bitcoin.

Counterparty: A simple description of it may sound like an “Ethereum competitor backed by Bitcoin blockchain”.

Siacoin: Distributed data storage. An alternative to Box, Google Drive. The big corporations would not have any access to your data in this point.

Lisk: A JavaScript-based Ethereum competitor that aims to make the deployment and development easy. Interesting solution for an internet of things device from a simplicity perspective.

I think it's intended purpose is supposed to be making token creation on their chain very easy. I suppose that puts them in direct competition with Ethereum and some of the Eth token ICOs.
However, there's projects like Zrcoin that are both tokens on ETH and on WAVES. So I think the business case is that if you want to create tokens very quickly - use Waves. If you want to do more complex things with the tokens (like using Solidity) - you could later somehow bridge your tokens between both Waves and Ethereum. I think the biggest unseen use case from that might be the commodities market, maybe even product inventories for companies at some stage.

If you are going to buy and leave it for a few years without trading it, I would recommend IOTA.

IOTA was developed by the IOTA Foundation is a “gemeinnützige Stiftung” (i.e. non-profit Foundation) located in Germany. with the aims to simply provide an IoT solution that leverages blockchain’s security and incentive mechanisms without the drawbacks of fees and transaction scaling.

To resolves the problems of transaction costs, scalability, and offline transaction, IOTA was hence developed. IOTA is a completely open source and a non-profit organization focused on building an IoT solution inspired by, but not based on blockchain technology.

Some say IOTA is new and there is a huge potential in its project. That is not entirely true. IOTA development began with hundreds of supporters back in 2015 and it has been covered in TechCrunch, VentureBeat, Forbes, Cointelegraph, CIO, etc. repeatedly. It is not a new project and they have been there for a while now.

Although it is not a new to some of us, in my opinion, IOTA is still far away from “mass-adoption”.

It can be happen if eveyone all around the world start to using Bitcoin. For using Bitcoin wallet everyone should have a mobile phone. As we all know now a day mostly peoples have mobile phone and everyone start doing small to big transactions by Bitcoin. So it can be possible that Bitcoin can make banks disappear.

Mining pools business is not considered illegal at the moment, and BTCChina reiterates that the BTCC mining pool service continue after the trading closure on 30 September. We have observed a turn of regulatory attitude towards Bitcoin and other cryptocurrencies. As 5 out of top 6 bitcoin mining pools are situated in China, it would be a disaster if internet connection of these mining pools were taken offline.

If you want to buy drugs or guns anonymously online, virtual currency Bitcoin is better than hard cash. Canny speculators have been hoarding it like digital gold. Now the world's leading bankers are even talking about as a rival for real money. How does it work, where can you get it and is it the future?

The first decentralized currency is soon to implement a contentious upgrade which fundamentally changes its direction from bitcoin cash to a bitcoin settlement network. A decision that may have ramifications for decades to come or it may amount to a storm in a tea cup, but does the way such decision was made suggest bitcoin has become centralized in the hands of a few people?

Do you remember 10-15 years ago when debit cards became popular and no fast food restaurant would accept plastic because fees were too high? What benefit did that have over cash? Simplicity. We moved money from a thing you had to possess (hard currency) to knowledge of a number (cc#). Now a majority of sales are plastic. The problem with pull transactions is apparent: fraud, minimal security, data breaches. Your numbers can be stolen. The benefit of bitcoin comes from the cryptography of digitally-signed push transactions.

The easy way to access your wallet if you are a trader should always contact your bitcoin every time. I can do whatever we like with it. Our money will be to their address, and they will manage them
I recommend using on your cellphone anytime anft but for personal computers

This is way overvalued. Be very careful in speculating this coin.Please Short it! IOTA is only for smart People Cheesy Cool

After the issuance of the token of the People's Bank of China (Tohoku) tokens, more than 40 ICO platforms have announced their inactivity. Banks also received instructions to stop providing services to ICO platforms. These services include: account opening, transaction, payment ... For current ICO accounts, the bank will check, assess the risk of hidden money laundering. If there is a violation, this account will be processed.
Although ICO is banned, many investors still believe in the development of blockchain technology behind Bitcoin. "Cryptocurrency is still worth the investment, what comes down is there."

It would be great When all nations accept bitcoin as a currency, to achieve it, certainly not easy for bitcoin and other cryptos.
Everything needs to be well known to the masses and easy to learn, Blockchain technology is representing a revolution and soon this revolution can go down to the application level where even schools can take advantage of.

As an investor, you should expect for risks like this, good times bring you many profits. Instead of questions you try to understand the meaning of bitcoin price fluctuations. Didn't you know that price decrease is giving us an opportunity to make again another rounds of buying. Also what you must look when you are holding bitcoin is long term goals and this price decrease can be recovered. Remember the recent price decrease just days ago, take it as reference, everything's assured that it will eventually increase again. There's nothing to worry, things like this is part of Bitcoin's volatility.

You can look over the HSR  It will give you the walls
or NEO, very suitable for short term investors.

Indeed, HRS is rising so high that profits are huge, there will be many short term investors selling it out and waiting for new opportunities.
Buying at this time will be high risk

That is impossible. And I never thought about that.

Only in some large developed countries, accept btc payment

It is both a currency and an asset that generates a lot of profits for you.

Following the Chinese government's announcement, all currencies fell sharply.
Now the coin is stabilizing again
