Same currencies are possible in regions that are economically similar. Like USA and Somalia can not have a same currency but USA and Britain can do so.
And there is a currency that is used all over the world too, Thats US Dollar. So there can not be one specific answer to your question thats why it is an interesting debate !

Bitcoin does not help anyone but Whales. Its the people that can turn up to help someone regardless of owning bitcoins.

Like Internet, Blockchain technology was also a revolution,
Internet is no more private, and for better privacy, we developed blockchain.
This new technology is not being developed by a single country or group in a single lab, but it is constantly being developed all around the world. So the question arises...... Who would fund this developement of blockchain ?
The answer is simple, Bitcoin and other crypto currencies are received by people who develope and the cycle goes on !

Ya it is a crime, because you can kill someone by shooting him with your 0.15 Bitcoin.

Bitcoin can never replace the banks. Because there are not much risk taking people like us. I like to keep money in bitcoins, but some people won't. So banks will always rule over cryptos. Thats the reality.

I trade at Bitfinex, I just started margin trading as my initial investment is reduced to 1/4 of initial total.
I borrow money there at 1:3.33 and trade with it.

Question # 1: There must be some interest rate or something like that which I have to pay extra on the borrowed amount but I never knew how much is it. and for how long I can hold that amount, not to incur further loss on paying that interest.

Q # 2: For example I had $100 and I bought 3 LTC with it @ 116$/LTC with leveraged fund. I put sell order @ 120$/LTC and clicked "calculate max. sell". There I was able to sell 5.6 LTC whereas I possessed only 3 LTC. It got me confused.
Furthermore, My sell order executed @ 120$ but it said my position was still open, and when I closed it, it actually executed @ 119$ rate and I got very little profit. I cant understand what happened there. Please help.
Thanking you in anticipation.

HA? please reply to my post what do you know about margin trading? what is your definition of margin trading?

(note Iam asking nicely here you might get mad of the words I wrote and might misunderstood me)

Because your just asking about trading not the word margin because "margin trading" is borrowing like getting money for trading to use it earn/for to gain income AND RETURN it back from the owner you got and accessing margin is using an margin that is an account.

Just to me it short and helpfull I would suggest you to go toooo Source

It never depends on trump or obama or anyone else, its the establishment making policy and running the country. The Senate and president are just the face, not the brain.

I am familiar with a concept of 'time value of money'. In margin trading, If I take that extra amount which exchange offers, it doesn't specifies any time limit for return, which in my view is necessary. What if I hold for 6 months, am I not liable to anything ?
I cant understand this concept in margin trading. Can anyone please guide and help me understand ? Thanks.

I always try to be informative and remain in the domain of topic, my post portrays my original thoughts and their length is also fair (100 words avg) pls I have also joined a campaign to earn merits BUT nobody ever considered me to give away a merit.
Am I doing something wrong here ? Hoping for effective guidance/advice or may be for some inspiration !

I think that the current dips in the market are artificial and result of some manipulation, They doesn't seem natural. I dont have a hard reason but I can say from my trading and TA experience that this is not what it used to be.

They could never 'Kill' the Bitcoin, some big governments like China have tried but seems like failed to do so, they can restrict the use, restrict the access but an individual will always find a way to access his account. I am not sure if a government can even impart Tax on crypto industry as there are always to perform anonymous transactions. So the answer is NO.
one thing they can do is to buy all Bitcoins, but the last few to sell bitcoins may hav millions of dollars for a fraction of bitcoin, even more beneficial for the ones hodling bitcoins.

Agreed ! You provide your E-mail and people usually use the same password for many accounts related to crypto, so it can help a hacker but I have a question.
What if I have 2FA security on my accounts which I have balance in ? I f hacker got access to my E-mail and password, can he move my assets ?

As the market is bearish now, so short term investment is not much beneficial now, but in long term, the future of crypto seems bright and will produce a good return.

There is No proper crypto bank uptill now, but there are many exchanges that offers some of the services that actual banks offer. They offer saving and current accounts in crypto and also percentage profit etc.
There is a guy I was once in contact with, who is determined to open a proper crypto bank providing all the services that a conventional bank offers. He has 350 bitcoins now and trading for some more, an has set a target of 500 BTC than he will start it and will obviously advertise it, then we are going to know a proper crypto bank.

Everything depends on the price of Bitcoin, because almost every coin is being traded in bitcoin. And here, all going up except the ones I am holding ! feels unlucky. But if bitcoin goes up, hoping for a better result.

Bitcoin and cryptos have unlimited potential and can go to unthinkable heights but it all depends on us. There is no real product behind BTC but its our money, our investments that makes it move forward, and if people start investing in it more, it can go beyond any limits ! So dont doubt the potential of bitcoin.

It is always a good time to invest in Bitcoin. You can enter into it and if you trade sensibly and technically enough, you can always make profits irrespective of market fluctuations and its current price. You just have to know when to get in, and when to get out.

The uses you mentioned here are there, but reality is that the most common use of Bitcoin is to trade and get profits from it. Simple.

I think the %age profit with bitcoin is quiet low, as in 6-8 %. But in alts we often see 50%+ rise in a week or so. Thats why I would prefer an altcoin for this investment and will bet on one of them. I hope that I get it right. Thanks for the suggestion any way !
