People want Bitcoin due to its transparency, security, ease of transfer, lower transaction rates and many more. People invest in Bitcoin basically to get huge profits. Some people use it in their business due to no involvement of intermediary banks and ease of transactions. People buy Bitcoin just like they buy gold and keep it until they are comfortable with the price and at the right time sell them to get profits.

Most of the people sell bitcoin basically to earn huge profits. They invest in Bitcoin when they are comfortable with the price and at the right time they sell them to get their invested money back with the increased price. Some people panic when the price decreases and think that it will not rise in future due to which they sell Bitcoin at low rate. But they need to be patient and let the price to go up as these fluctuations are normal.

Its a great news for those who really want to invest in the Bitcoin. Its price is gradually increasing and i think it will reach $40k by the end of this year. So just don't think and start investing, you will definitely earn huge profits.

Various advantages of bitcoin are:-
1. Non Changeable Transactions: It means that once the transaction is made it cannot be reversed like it can be done in the bank payments where the user can reverse the payments.
2. Quick and Cheap Transactions: There is no fees or minimal cost for bitcoin transfers while if a person transfers money using credit cards it costs him 3-5% of the transfer amount which is way more than bitcoin transactions.
3. No Tracking: No one can trace one's transactions unless he makes his wallet address public. Even if he has made his address public no one is able to see how many bitcoin he has but the owner can.
4. No Stealing: One cannot steal bitcoin until and unless he or she has the physical address of the owner's computer and send the bitcoins to their accounts. It is difficult to get the physical address, which makes it harder to steal bitcoin.

Bitcoin can be considered as a money but a digital currency. All the transactions that can be made using Bitcoin or other cryptos just like conventional money but without any intermediary banks. Just the difference between the two is that Bitcoin is the result of mining process while other money is prepared by commercial banks.

Yes definately you should invest in bitcoin as you can see the skyrocketing price graph from starting when it came into the market till now. Its beneficial to invest in Bitcoin but one needs to be patient as there can be rise and drop in price, so don't rush into things you will be definately benefited by investing in Bitcoin.   

I think major benefit of bitcoin is its usage. Its easy to use and there is no need of any type of ID proof for using bitcoin as compared to the conventional banks that require number of proofs while opening an account. Also there is no age limit so anyone can use it. Most importantly No paperwork is used in this process so i think it is environmental friendly as trees are not cut for paper to keep records.

Its not necessary that if you are old then its too late for you to invest in cryptos. As there is no age of learning so anyone can understand what these cryptocurrencies are and can invest in them. A person despite being old can understand and invest in cryptos if they are familiar with internet and are ready to understand. Yes, it is bit difficult to understand cryptos but the most important thing is their will. So, anyone can invest in them whether young or old.

Yes Bitcoin can definately survive. We have seen gradual increase in the usage of Bitcoin and other cryptocurrencies from the past few years. It is efficient, safe and reliable. Now days most of the business transactions are carried out using these cryptocurrencies as it is easy and fast, moreover there is no intermediary between the transactions i.e it is peer to peer transaction. More people are using it day by day so i think Bitcoin will definately survive in future.

I think Bitcoin should be called as an asset rather than a currency as everybody knows that Bitcoin is a cryptocurrency and worldwide payment system and cannot be kept as ordinary money. Moreover people preserve Bitcoin as a useful thing so that they can use it in their business transactions that is safe and transparent or keep them in order to earn huge profits in future. Also the price and use of cryptocurrencies among people from past few years has increased gradually especially Bitcoin that it has now become an asset.
