Bitcoin is a currency which is regulated by the people or we can say its price are determined by he indivduals. so users definatel play a vital role in the existence of bitcoin.

main challenge faced by crypto will be artificial intelligence and moreover govt regulations is also a important challenge for cryptocurrency in near future

well yes it may be the fastest way to get rich but it depend on various factors like how long you are in cryptocurrency? how safe you are playing ? do you know do's and dont's of cryptocurrency investment ? it vary from person to person

well in my opinion all ico may not be profitable it depends upon how people take that ICO . None can decide the future of one or other crypo coin

well not sure that whether litecoin will be next bitcoin as there are numerous cryptocurrencies , also their value keeps on changing so no one can actuly tell which coin will be the next bitcoin.

Yeah very true in these digital or cashless world bitcoin will not only survive infact it will grow with very fast pace .

Yeah people still have faith in bitcoin , its just like nonending currency whose value can only increase or decrease but cannot vanish

No not at all bitcoin is a digital currency also known as digital crytocurrency . Digital gold i havent heard anywhere its something else people are imagining.

cryptocurrency is a long term investment and it give good profits in long term as compared to short term.

I think all those who owns some of the cryptocurrency to themselves individually , they all contribute their share in controling cryptomarket.
those who owns it controls it.

In my opinion bitcoin should be taken into consideration by the government and should be regulated

Bitcoin is a virtual money till now also its value keeps on fluctuating which cause much risk in market moreover its not official by the government of any country so thats why it cannt be used for medical billing.

In my opinion bitcoin mining doesnot uses much energy or electricity instead the electricity used by use in our homes or offices or public places like banks, cafe etc are much more on higher side than bitcoin mining. moreover it doesnot cause any harm to our computer systems also.

Bitcoin is itself a currency and is used ahead of physical currency . In my opinion bitcoin can replace physical currency in coming few years. As in this digital era where digital transaction is being prefferred why would one will carry  paper currency when they can travel around the world without them also and that too easily.
