Bitcoin name is very familiar to those who try to know regularly and constantly in the online world. Everybody is curious about Bitcoin - Interests. I would like to talk about how much bitcoin really is. Actually, how confident Bitcoin can be for the future. But before, find out more about Bitcoin and Bitcoin Mining.

First of all, the way Bitcoin dollars, euro like currency, they are absolutely wrong. Bitcoin is not a valid currency. Bitcoin is not like a currency or a domestic currency. Bitcoin is dependent on one type of investment. Bitcoin's market value is rising on the amount of people who invested. A currency or currency, such as a dollar, euro, Dinar has a steal value and it is never more than that, but Bitcoin is quite upside-down. Bitcoin has always been like gold, it does not always have the same value. Bitcoin is any currency in the same way.
Bitcoin's value
Bitcoin's value has been fluctuating for a while, because many people are interested in Bitcoin and its desire for investment is growing at a very high rate. On 6th December, the price of 1 bitcoin was $ 12770, just 24 hours later its price rose to $ 16583. Again, on November 8, the price of Bitcoin was $ 7458, which dropped to just $ 4,857 in just 4 days, which means that there is a shortage of bitcoin prices here again. But in December, incredibly high prices of Bitcoin are being noticed. From 3 December to 6 December, within just 3 days, Bitcoin has risen from $ 11180 to $ 12168. That is, at the bitcoin rate, we can easily see a very big rise.

Transaction speed of Bitcoin
So I got the idea of Bitcoin's rate, come to the original top. How much is investing or investing in bitcoin? How safe is it? What is the transition in bitcoin credit card or online payment system such as Paypal? No, Bitcoin Transaction is a lot of trouble. To break your Bitcoin from the dollar, you will have to pay the money to them, where you have stored your bitcoins. Bitcoin Transaction here is not just expensive, it is very time consuming! A bitkayen takes approximately six hours of transaction, maybe more.

If we think about it a bit more then we will understand that a bit of coins are not complete but the cost of electricity is reduced. For the transaction of bitkayen, the request is confirmed from some networks, several data is encrypted, some work behind the working computer, etc. You may be surprised to know that the amount of electricity consumed by a bitkayen's complete transaction, the electricity cost of America's home, And these are the reasons why Bitcoin Transaction is a bit more costly.
Bitcoin is illegal in Bangladesh
Bitcoin is a thing like a banned place, that means it attracts you, but if you accept it, then what is going to be unknown, you will not be able to retrieve if you catch up with Batper or any other danger. And the hacker, because of the fact that Bitcoin is constantly being hit by the spammer, many people have to face losses.
In the event of 2014, the biggest Bitcoin exchange in the world's time was caught by MTG hackers and they were stolen by the hackers. Their 850000-bit coins were stolen, and whose value was worth $ 450 million, but now its value is about 8 billion dollars.

There is no legal aid available for the payment of bitcoin payment, any problem related to transaction. Although MTGX has been hacked for the Bitcoin to be hacked, even though they did not recover a single penny and they had clients, those whose money was deposited in MT.Gox never seen their investment or deposited money.
Thus, every BITKEN related organization is not safe in any way. And Bitcoin is not a valid currency in our country, because of which many revenue losses of the country are being made. Either you buy Bitcoin or if you face any problems later on, you do not get legal support, you can also get into trouble.

Finally
So, we have been clear about two things about this, one is that Bitcoin's value is unstable or its price may be more or less at any time. Profit - losses are equal to two. And its transition speed is very slow. It is illegal! But people want to invest in bitcoin less for transaction, more to gain. Many people invest only 20 thousand rupees and then it costs up to 1 lakh and it does not take any time to 10 thousand. But sometimes it is beneficial to invest in bitcoin but it has to face many problems to get rid of it. Many times those who want to convert Bitcoin into dollars or other currencies, are framed. Another problem is that bitcoin transition speed is too much.

We use bank cards, such as debit cards, credit cards, etc. regularly. And sometimes there are many problems in payment of payments. Then we have a system for online or phone support, we can let them know, whether it's too little or something else. But there is no such facility at BitCoinware interface. If your payment is inked in any way, the money can be lost. So, the possibility of profit by investing in bitcoin, as far as possible, is more likely to cause problems or losses.
