I believe that at the moment they can be called king and queen. But with the development of the crypto currency, other coins may appear, which can replace both bitcoin and ethereum.

Every new trader makes a lot of mistakes. you should not regret the loss of profit, you should rejoice at the successes that have already been achieved. When you have more experience you will be able to feel the market and get the most out of it.

In my opinion, the market slowly but surely grows. I think this may be the beginning of a new era, but everything will show the time.
I am very happy when I see how the market is growing. I really need to give them a steady income like giving them a business.

I think Stablecoins have to reach the point where crypto payments is their main (or one their main).
Of course not to limit their utility, and I don't mean it should only used as payment method. But the price fluctuations on BTC, ETH, LTC etc, are huge and it will take a lot of time, money, effort for them to be traded like in a usual "normal" market.

Neither climate nor resources – solely education is key to humanity’s survival. It is about time to invest into education globally, since without it, there will be no survival. The fault lines of the 21st century run between the well-educated and the uneducated, between societies of knowledge and those that obstruct or even thwart access to education.

I buy altcoins because I believe in what these new coins may do in the future. Just like the internet, we had improvements and new competitors in the market.
This stuff is early and we have no idea really what things will look like when we start seeing adoption, at the moment all these altcoins are based on potential

Here are some common features to look out for:
Guarantees of high profit/interest rates

Ethereum is not just a digital currency. It is a blockchain-based platform with many aspects. It features smart contracts, the Ethereum Virtual Machine (EVM) and it uses its currency called ether for peer-to-peer contracts.
Ethereum’s smart contracts use blockchain stored applications for contract negotiation and facilitation. The benefit of these contracts is that the blockchain provides a decentralized way to verify and enforce them. The decentralized aspect makes it incredibly difficult for fraud or censorship. Ethereum’s smart contracts aim to provide greater security than traditional contracts and bring down the associated costs.

One of the most widely publicized benefits of Bitcoin is that governments, banks and other financial intermediaries have no way to interrupt user transactions or place freezes on Bitcoin accounts. Bitcoin purchases are discrete. Purchases Are Not Taxed. Very Low Transaction Fees. And no Third-party Interruptions

We do. Most altcoins are peer-to-peer, involve a mining process by which users solve difficult problems to unlock blocks, and offer efficient and cheap ways to carry out transactions on the web. But even with many overlapping features, altcoins vary widely from each other - altocoins differ themselves from bitcoin with a range of procedural variations, including different proof-of-work algorithms, different means by which users can sacrifice energy to mine blocks, and application enhancements to increase user anonymity.

Long term? It all depends on what the governments are going to feel. That’s important for valuation of any asset, including cryptocurrencies. But there are lots of potential feelings and lots of governments. Specific resolutions favor some cryptocurrencies over others. But any plausible resolution leaves significant value for at least some cryptocurrencies.

Iran is governed in accordance with Islamic laws, which heavily regulate the banking sphere. In general Islamic economists ban everything that is not created by work. You cannot make ‘profit out of thin air’. To my understanding, to a certain extent cryptocurrencies fall into that category.

The crypto market moves in cycles – and understanding these cycles is key to profiting, managing risk and keeping sane. (1) Hold more of the things that rise and less of the things that fall, and (2) cycle adjustment, or trying to have more risk exposure when markets rise and less when they fall. Stick to this and then everything will be fine.

Blockchain enthusiasts see the technology as a way for Facebook to address and solve many of the recent problems it has faced concerning people’s privacy.
While there are other cheaper and faster alternatives for protecting user privacy, blockchain allows the users to control their data end-to-end. This might be an attractive use case for Facebook, considering the recent Cambridge Analytica scandal.

Bounty campaigns are definitely not a waste of time! They are great opportunities for income and to be able to provide service. A lot of lives have greatly improved because of bounties and a lot more are gaining.

In my opinion, crypto is the future but will have peaks and valleys like the stock market.
I want to hope that in the year-end position will be played back and we will be able to enjoy the profits if of course, we managed to buy in the red market.

In my opinion even the most reputable bitcoin exchanges are suspect. Not because of intention but because of the many ways an exchange is subject to attack. An onsite wallet service is no better. Anything that touches the internet is susceptible to assault.
