It's a Very Struggling time for Cryptocurrencies. The Market Goes down approx 10 to 15 Percent. Bitcoin Drop down $7k, On the other Hand, Ethereum goes down $400.

Paper money will not have a good future. Paper money will die. You know what will happen with Bitcoin, Bitcoin will always exist. You can of course see now that Bitcoin is more used now, and that is good.  you know Bitcoin will happen nexy real money.

You are right .Bitcoin is a Currency. Its value constantly changes. Those who strongly believe that Bitcoin's price  will increase , they will buy Bitcoin. When its value increases, they can earn good profits. Bitcoin's value increases when its demand increases. Bitcoin earns a lot of profits because you have achieved success in life. Bitcoin can change your life. Now, Bitcoin is worth less. The price will rise soon after. So, to earn more profit, Bitcoin is buying low prices for many more profits.

I know right now nothing is like bitcoin and the ETH but mate I only love the bitcoin, no currency can be like bitcoin ever, price of bitcoin use to change very fast, once it is low then after very short time it will increase once again, my all the time suggested investment is only and only bitcoin, bitcoin has very large scope in market now, and it has very high demand as well. More and more people are attracting toward bitcoin so I would prefer one and only bitcoin, which is the king of all other crypto currency and it will remain number one and my first choice forever.

They say that bitcoin is the future of money. What do you think if we use bitcoin in everyday lives as a money? Like buying foods. Or buying clothes. Do you imagine it positively or negatively?

 i think Bitcoin is only profitable if done at large scales. you must get expensive mining equipment and of course it consumes a lot of electricity monthly. Also it’s usually much more cost effective to buy Bitcoins with this money instead of using it to buy mining equipment.

As I have seen this already too many times since past few years, I believe it would be beneficial to share my experience with crypto markets. Do not sell your coins/tokens when the market is dropping, it's just a pure speculation and perhaps market manipulation from whales who only target to earn on whatever the price moves they can achieve. If you're reasonable, sell when market is high and buyer/hold when market is bleeding. I hope this helps you to decide 

What do you think about the fact that cryptocurrencies will literally be the future ? In a few years, it will exploded and, be rich if we hold many ?

Would banks and governments actively work and implement countermeasures to undermine this process? Are the underestimating the potential of cryptocurrencies by investing in some of them?
Do you think there is a possibility of cryptocurrencies being banned in the future for the reason of being a threat to "normal" currencies?

yes Bitcoin and Altcoin will go up again. do you know that no one can predict the Cryptocurrency price correctly, because we know the price of crypto is very fluctuating, can go up and down very quickly. that means even though now the price is falling very deep, who knows one more month the price will rise high ??! that's what makes me very optimistic, and keep investing in Bitcoin.

People think that gold is better than bitcoin, because they can see and touch it physically. But the world is changing. And the digital currency is our future.

It seems like only a small fraction of bitcoins as well as other cryptocurrencies gets earned while the vast majority of the coins are bought. But when people buy coins, they obviously aim exclusively at selling them later at a higher price, which is what speculation basically consists in because it makes no economic sense to buy a cryptocurrency to spend it on goods when people can easily spend fiat instead. However, if the price goes down, people aren't going to spend their coins either. And whenever someone complains about prices going down, the only reply they receive is just to hold to their precious bitcoins, no matter what the price could or would be. I have yet to meet anyone telling these bag holders to spend their stashes on something useful.

Apparently, the HODL mentality kills the currency aspect of Bitcoin.

The sharing economy is just going to continue to grow, and governments will be challenged to understand and manage its implications while embracing its benefits. However, governments will be at a significant disadvantage if they wait too long and newer technologies and markets will have already been developed that do not follow traditional models. Think of the following: Uber is the world’s largest taxi service and owns no cars. Airbnb provides lodging yet does not own real estate.

How will local governments adapt to these new ways of doing business that are disrupting traditional business models? All we know now is that governments are a long way from even contemplating and accepting this new reality.

Hodling doesn't means picking any shitcoin and investing your money in it and just waiting. When someone says hodl they mean it for a coin which has great fundamentals, a sound dev team working for it and the project has real world use case.
