If a whole inhabitants of a country becomes a completely cashless society, then there is no need for fiat because all transaction are fully digitized including their national currency. A currency like dollar can also converted into centralized virtual currency by the US Federal Reserve  to match the growing popularity of decentralized cryptocurrency. Both digital currencies created by the government and cryptocurrencies will be used by the people according to the benefits that can be available from each currency.

You can't prevent people from predicting or speculating the future outcome of a cryptocurrency because it is been part of the trading. But believing or in the so called crypto analysts and relying on them is not good for your trading career. Cryptocurrencies are unpredictable because of their unstable prices andno one can exactly predict their future prices. I'd rather study the behaviors of cryptocurrencies and the whole market than relying on predictions of others.

Most of the experienced traders and investors are using that researching strategy tofind the right for their trading. Researching is really a valuable tool these days because of the proliferation of scam coins and ICOs. The beginners should learn first the basics of cryptocurrency and trading including the need to to do a research first before making a trade.

I think if someone is determined to become a skilled crypto trader, there is no such thing as bad luck because losses are only temporary. But rushing to become a trader is not a good idea, you have to learn it first and give it a significant lenght of time to become an expert in trading. Trading is always risky so you must be a risk taker while you are still active in trading.

Ethereum's future is still promising even its price fell down below $100 last year because its developers are always active in improving its features. The current price is still lower and still the best time to buy if you are planning for long term investment because it is safer to hold than some altcoins. The forthcoming hardfork of ethereum this year and other developments next year will have a positive impact on its future price so it better to buy and hold ethereum.

It will depend on the quality of the coins you are holding, if they have the potential to go up in the near future then you must hold it more. They are only few cryptocurrencies that are good for long term investment so you have to do research for the coins first before you start buying. If the market will go bullish, almost all coins will go up inluding those newly listed in the crypto exchanges but it is uncertain if bullrun will happen this year.

Ethereum price is getting lower again after its hardfork postponed and it is a good opportunity to buy the coin at still affordable price. I believe that the price of the 2nd ranked coin will bounce back in the near future again so this is the best time to buy it. Ethereum has been proven for its ability to recover from a correction or price decline and its forthcoming hardfork might also help boost its price.

I think whatever happens to approval of ETF and the launching of BAKKT, the effects on bitcoin prkce might be minimal. The big-time investors or whales will have the final say whether the bitcoin will going to moon or not. If these influential investors decide to push the market up, they will going to do it anytime because they have the resources.

If the government will found out that there is a valid necessity to create their own cryptocurrency then they will going to create it. Venezuela their first government-madecryptocurrency called petro and it is backed by their country's oil reserve but many analysts believe it will going to fail because of poor management and misleading white paper. Cryptocurrencies that will be issued by wealthy countries have the big chance to succeed because they have enough capability of raising funds for their centralized coin.

I don't expect bitcoin bullrun this year but there may be a modest growth for the top coin this year. There are still a lot of market uncertainty for this year starting with delayed BAKKT launching and the always postponed bitcoin ETF approval with some of them already rejected. This events might affects investors' confidence and market growth temporarily but I believe many of the altcoins are poised to go up this year with their own mini bullruns instead of bitcoin.

I agree with you, ethereum will be having a hard time to overtake bitcoin even in many years to come because of large market capitalization, price gap and mass support. Ethereum should maintain its rank in second place first because the threat of ripple to overtake it again is always there. Ripple's future is promising because many global banks are joining the fray and ethereum should continue to improve itself to counter the growth of ripple.

Learning to control your emotions is one of the best antidote for getting addict in trading. Although it is hard to do, it is still possible if you have the determination to become expert trader someday. Many traders lost some significant amount of money because they can't able to get rid of their emotion when trading. Try to exercise extreme discipline and strictly focus on your trading strategyinstead of using it like a gambling..

Of course not, I think it is not also advisable because trading cryptocurrency is very risky and unpredictable. I'm still going to stick to the advise of some expert traders of trading only the money that you can afford to lose. There are many ways to fund a trade but funding a trade through a loan is not a good idea because of the nature of the cryptocurrencies. Loans is best use for business ventures where profits is sure to come if you manage it well.

Lack of good news or positive developments related to bitcoin is also one of the reasons of its price decline. The continuing rejection of SEC for bitcoin ETFs can also affect the price of bitcoin along with FUDs which have spreading fake news in the internet. The trade war between US and China is over because there is already high level talks to solve the dispute. Bitcoin price will continue to face some more declines in the future before the steady rise.

Social media is one of the efffective tools in spreading the news on bitcoin and other cryptocurrencies and I've been doing this since I started using bitcoin a couple of years ago. Some of my friends don't like the idea of a currency that can be use only when you are online but after they've their own research, they are now planning to buy bitcoins. They are many ways to the spread the use of bitcoin to speed up its adoption and it is up to the people to do their own.

Their game might be over but not bitcoin because I believe there will be more high growth to come in the future. More investors including in the financial sectors are planning to buy the top coin so it is not possible to end this year because of price declines. Price declines are only temporary and they are part of a cryptocurrency price cycle so after an uptrend, it always followed by downtrend and vice versa.

The market situation for the year 2020 is still remain to be seen and there might be some developments that may happen along the way. The market is unpredictable but i believe it will not going to remain mostly bearish before 2020. Several factors like the launching of BAKKT and ETF might push the price of the bitcoin up this year. There is a possibility that several coins, not necessarily bitcoin, might lead this year's price rally.

I think bitcoin and the crypto market will recover later so I have to remain positive on its future. Bitcoin has its own price declines before the 2017 bullrun and several of them are price crashes that made the top coin seems dying that time but it bounces back and reached that all-tme high later. Try to remain positive about the future of the market because there is a right time for another bullrun.

Lack of proper knowledge is one of the reasons why people refuse to use or accept bitcoin. Others might be afraid of the risk its contains like high volatlity and rapid price fluctuations. The media reports of some criminal elements that uses the coin to scam people might add to the fear of those who want to invest in bitcoin. Everyone who want to get involve in bitcoin should learn the basics of cryptocurrency first.

Cryptocurrency have been unpredictable so we must also expect the unexpected and yourself prepared emotionally and financially. Some of the investors that lost some significant amount of their investments never recovered because they sold their coin in loss believing that bitcoin will never recover again and they are even gave up on investing in a cryptocurrencies again. I think these kind of investors are not prepared well and with only little knowledge on cryptocurrencies.
