Fees will continue to increase. For a "fee market" to evolve, there needs to be demand and suppliers. But there is only a fixed supply.
If fees get high, there's no way for miners to say, "Oh fees are high, we should mine more blocks or larger blocks to capture these fees". So fees continue to increase because demand is just slightly higher than capacity.
 Anyone who has ever used the phrase "fee market" with respect to a fixed block size has no grasp of what is and will occur.

 The only damage these hacks cause are reputational and of course, material damage in a sense of stolen funds. Cryptography and blockchain are unhackable (at least with the technologies and hacker knowledge of current era).
 That is why we need changes in the cryptocurrency ecosystem. Centralized exchanges need to be dethroned and put down the pecking order in the hierarchy.

I believe in the technology. I believe there's a need for decentralised systems like this where probably the majority of people don't have a bank account.

I live in the UK and I don't trust my government to run our economy effectively. Austerity has slowed our growth to less than any comparable countries. We're leaving Europe and that's going have a negative effect on the value of the money I own.

Is it to late to invest?if your thinking you can get past returns,yes.Bitcoins were hyped up and people jumped in,the price skyrocketed.The problem is the only people who made real money were those who bought low and sold high.Most people who jumped in at peak either lost money or are holding coins at lower market value.

 A cryptocurrency is a form of payment which is similar to the currencies commonly used such as United States Dollar or the British Pound. However, unlike these currencies, cryptocurrencies are decentralized. There is no central government to print more of them out to cause inflation. In fact, cryptocurrencies have been formulated to gradually decrease in production as time goes by. Bitcoin, for instance will never have over 21 million coins in dissemination.
 Cryptography is used to ensure the security and privacy of transactions and exchanges, and to regulate the creation of new coins. Cryptography was developed during the Second World War, after the need for secure communication arose. It has undergone many development with elements of computer science and mathematical theory, and now it is used in financial system for decentralized currency.

The bitcoin transaction does not reveal identity info. The purchase can be connected to you, only, if the merchant keeps a record of the transaction id connected to a goods receive address. Online goods are sent and the IP address is recorded. In this case any vpn provider can help you to keep IP information out of reach. The bitcoin transaction by itself, does not reveal personal information. Personal information can be revealed by looking for other data that are connected to the transaction.

As everyone knows bitcoin is a cryptocurrency and it is the recent unique financial system. Anyone with an internet connection can send and receive bitcoins easily hence bitcoin trading has become popular. Also, bitcoin trading doesn't have any transaction fee. Thus bitcoin trading is the best mechanism for online payment.

Digital currency is any form of payment that exists purely in an electronic form and is not material like a dollar bill or a coin. Digital currency is transferred between the participants involved over the world wide web whereas virtual currency is essentially a toy. As the word virtual suggests, this currency is not meant for use in real life.

Cryptocurrency or as some call it “the unicorn currency” is based on a peer to peer electronic cash system. A dramatically transforming money settlement method, cryptocurrency doesn’t involve any third parties like banks or the government between the two parties concerned.

A threat to the existed financial system, especially the banking system. However,what we also need to know is that quite a large part of India people has no bank account, which is sure to be rather profitable. With advent of cryptos and blockchain technology increase the competition to attract users of this sort to open a bank account and deposit or transfer their money in the system, for the new technology is in fact a lot more convenient compared with the processes in banks. What’s more, it’s commercial banks that the RBI uses to perform policy and regulate the whole market. If capitals are all flow to a system that beyond the supervision of the RBI that it’s certain to overburden the Reserve Bank to discipline the financial ecosystem.

In conclusion, the reason why the authority of India finally decide to crackdown the market boils down to its potential nature as a spam and threat to the local market and finance.

Both are and crptocurrency as a whole is extremely volatile.
As a noob you are likely to lose the shirt off you back and have your skin flayed.
It can be a fast path to quick riches but given that 85% of traders don't make this trading thing work. There is an extremely high probability that you will fail and fail fast.
Good luck

Might I suggest, you will kick yourself for not in investing in them now in ten years from now. Let me focus on Crypto in this answer.

You cannot ignore Crypto – the major players – Bitcoin, Ethereum, Ripple because Bitcoin alone is valued at $80billion according to Bank of America Merrill Lynch. Although there are a thousand coins out there, these are key and the bank says the reason these are important is because they have distinctive features and “Unless a coin has some distinctive feature, we think it may struggle to gain mass adoption.” Bitcoin’s objective = decentralised payments. Eth objective = “smart contracts” and Ripple = forex trading infrastructure.

India and all other countries have taken an initiative to include the field of (KYC) in cryptocurrency buying and selling wallets. Meaning everything you buy and sell can be tracked. So, there is no reason for india to ban cryptocurrencies.

Yet some of them like bitcoin etc can be banned because they are just a cryptocuurency.

Ethereum wont be banned because it is a smart contract platform. And it has changed the world of information technology a lot. So to conclude if you choose to invest in Ethereum, you’ll definitely profit.

 If you want to invest then the top 5 or 10 currencies right now are probably your safest bet. Ethereum has established a brand by now and has a working product. That is not the case for most altcoins right now. Ripple is also one of the few projects that has a working product that has been adopted by Santander bank and currently tested by Western Union that also plans to use their product.
 If you are looking for something that is similar in functionality then Litecon is as close as you can get. It is created as a digital currency, just like Bitcoin but has faster and cheaper transactions. I know many people will also mention Bitcoin Cash here but I would avoid that at all costs. These people are trying to convince users that Bcash is actually Bitcoin. That is not the case. Bcash is a fork of Bitcoin, nothing more.

~90% of people trading assets lose money because (a) they have no long term plan, and (b) because they have no plan, they constantly feel stressed about their holdings and market volatility, and (c) that stress destroys patience and inevitably leads people to make bad trades.

The successful traders who constantly make money, do so because (a) they have a plan, so that no matter what way the market goes, they're ahead, and (b) they cost average, and (c) because they have a plan, they aren’t stressed all the time, but are ready to act rationally at the right time: Bitcoin is crashing? great, let’s buy a little. Bitcoin is spiking? great, let’s sell a little; and (d) they aren’t following the crowd.

It is the future and it cannot be ignored anymore. Such statements like it’s a scam or how stupid you should be to get involved in cryptocurrencies aren’t worth anything. Expand your knowledge, do your own research, and at the end of the day, I am sure you will see that this technology is great and changing the world.

Currently trading crypto is considered a like kind exchange so no capital gains taxes are due (there is some dispute with this but the irs only guidance seems to reinforce this) . You only have a taxable event if you sell crypto for cash. The reason is the idea of a like kind exchange which basically says you arent really selling but rather keeping a different form of the same kind of thing...a "like" kind.

The new tax bill would make it clear that like kind exchanges are reserved only for real estate thus any trade of a crypto currency would not be considered a like kind exchange and taxes would be due.

I think your main concern refers to mining and the (excessive) electricity spent on it.
However, everyone doing mining actually pays the price. So this become an ethical question and concerns not only bitcoin, blockchain and mining, but also the general environmental attitude we have towards our planet.
So should we stop bitcoin mining because of the environment?
I think we have more serious environmental concerns to be worried about right now! And bitcoin mining is the last one in that list!
