If gold is better that is because it is a precious metal since always. Gold prices have always gone higher and higher rising from approx 3000 per 10 grams in 2000 to 27000 in 2017. As the gold reserves will be reduced, it will lead to higher prices of gold. This enables people to gain profits from gold. But these BTC are also going popular in terms of giving profits to the people.

Both have their pros and cons. Mining is profitable if there is price surge but on the other day it is time consuming also and require technical skills. Buying is nothing technical, all you have to do is buy the bitcoin and then the circle starts. Moreover this is not risky whereas mining is. But you should buy the bitcoin when the price is low enough to give to profits later.

Yes, it is true that the limit to bitcoins is 21 million. After that no new bitcoins will be mined by the miners. Bitcoins will still be in use via transactions. But this will take a long time to reach this value. Still millions of bitcoins are yet to be mined.

It is most popular cryptocurrency because it is the oldest one. Originally it was invented by Satoshi Nakamoto. All other alternate cryptocurrencies came later. And also these are named as "alternate" which gives bitcoins as a status of being the major one.

Not really. It is just a fictional name used by the team who developed the concept of bitcoins. They kept themselves by taking this name . The person was not seen .

Why do we need AI? : Are we destroying ourselves?
Artificial intelligence is the mutual branch of both computer science and engineered
robotics. Artificial intelligence is ideally a computational machine consisting of highly
programmed software with vital abilities to understand and interpret natural human
language, sense and speech, logical thinking and most importantly learning not only
through data, but also observations. It emphasizes on the creation of intelligent
“machines” that deal and impersonate just like humans. Advancement associated with
AI is highly technical and specialized. Core problems in making an AI in relation to
computer science are knowledge engineering and machine learning where as in
relation to robotics core problems are object movement and manipulation, navigation
and motion mapping.
Today, the breathtaking examples of AI like Sophia (first robot citizen of the world) and
Google Deep Mind are changing the way we look the automation. From intelligent
phone assistants (SIRI, Cortana) to self-driving cars, AI is progressing rapidly.
Meanwhile science fiction often portrays AI as robots with human -like characteristics ,
but that is the not what the reality portrays. Engineers and scientists are still trying to
reach a point that would be considered full artificial intelligence, where a computer
could be said to have the same cognitive capacity as a humans.
But, I believe it’s good that AI is not the real ity. Many Scientists and thinkers have
argued over the advancement of the Artificial Intelligence. Thinkers like Hawking and
Musk have expressed concerns about "super" artificial intelligence that is intelligence
that could equate or exceed that of a human. Even today proto AI (not fully AI but beta
versions of AI) examples are creating problems for humans. Robotic AIs are taking over
our jobs and increasing unemployment at an ever extreme rate.
Some thinkers also believe that AI intelligent enough could possibly outrage human
race. A dominant “super” intelligence could conclude that human survival is an
unnecessary risk to them or a waste of resources, which would actually pose a risk to
mankind. Any substantial progress in AI could someday result in irrecoverable global
catastrophe.
One of the reason why everyone believe that AI will outrun us is because of our basic
nature towards another creatures. Humans have well-developed brains and distinctive
capabilities which allow to be dominate other creatures. Dominant Intelligence and
smartness, even helps us to control tigers and elephants. In the same way, If AI
surpasses humanity in general intelligence and becomes "super” intelligent, then it
could become powerful and difficult to control, hence ultimately ruling over humans
and may be much probable extinction. This hypothetical scenario is referred by
scientists as “Intelligence Catastrophe”.

Egg came before chicken. It was scientifically discovered last year that egg contains certain compound which is necessary for chicken to be born.

Though i am single yet but i have observed and can well imagine the life before and after the marriage. Before marriage , you are independent and your own master. After marriage , you become dependent and restricted. Before getting married you just look into you and your life but after getting married, you also have to see about your spouse and his/her family.

Definitely there should be women empowerment. There is still hardly any place where women get more rights than men. Men are treated higher in families, in society, in work places, in politics, in education , rather everywhere. Why are women left behind everywhere? Women should be given more power so that they can also live their life at par with men. Women should be given rather more rights than men so that my actual implementation they can at least come closer to the level of men.

A place that w person wants to visit depends upon the likings. If he likes hilly areas then visit Srinagar, Shimla, Darjeeling, Ooty, Nainital, etc. You can visit Taj Mahal , Golden temple, Mumbai , Jaipur, etc.

Bachchans have such a huge profit and it attracts the People to the arena of bitcoins. They invested $250,000 in meridian tech ,which mounted as high as $17.5mn . They came to limelight when bitcoin value rose to $20000. It truly justifies the saying 'small investments and big returns'. So many people came to know about bitcoins after this news came out.
