Many of the traditional financial players, including JPMorgan CEO Jamie Morgan, have criticized Bitcoin, describing it as a bubble. However, due to its hierarchical, mathematical and transparency nature, so called Bitcoin is a very inaccurate bubble of any kind.
Tesla, Amazon, Bitcoin "Bubble"
Bitcoin is not a bubble, contrary to the dishonest and unrealistic claims of bank executives. There is a bubble in Bitcoin in 2013 when demand for Bitcoin increases to a point where the market can no longer support it and the Bitcoin price has fallen from $ 1,300 to $ 200. However, it is not accurate to call the release. Bitcoin body is a bubble, like the inaccurate way to describe Amazon or Tesla as a bubble.
Even up to April of this year, analysts describe Tesla's exponential increase in the value of a "bubble," as analysts have done with Amazon over its 20 years of the company. about existence. Six months ago, Matthew Debord, shipping editor at Business Insider, wrote:
"At this time, a Tesla bubble looks clear and seems clear as it has since the beginning of this year. The difference now is that it grows so big that it becomes scary. "
A "expert" David Greenfield's Greenlight Capital, claims that Tesla is a bubble that will not turn up anytime soon, but it is a bubble. "In due time, we hope the bubbles to pop," Einhorn said.
It is important to acknowledge this trend in any emerging technology company and launch. Analysts and experts rush to confirm that anything is a bubble, due to its rapid rise in value and exponential growth.
From 2013 to 2017, Tesla's share price has risen from $ 20 to $ 302, with many minor adjustments and adjustments. In December, the Tesla shares fell more than $ 100, from $ 250 to $ 150, due to the company's troubled finances. However, over time Tesla recovered and it developed a sustainable business, a market, and extremely important, a consumer base similar to the way Bitcoin has evolved into a sustainable financial network, a strong market and secured an active consumer base of tens of millions of users.
Moreover, it is far from clear that the Bitcoin market, which includes a similar volume and liquidity of Apple, the largest liquid stock in the world with a daily trading volume of $ 3.3 billion. , because it has grown significantly since it was introduced in 2009.

Bitcoin fees are decreasing:
- Fewer transactions result in lower transaction costs, which ensures that users integrate their bitcoin (BTC) into their SegWit account. Transactions from a SegWit benefit from lower transaction costs.
- Some commercial players have begun to see the benefits of using a BTC as a coin, though Steam and Stripe now reduce the cost of bitcoin payments and its volatility. Both companies accept bitcoin for bulk transactions, low value, and will continue to use bitcoin as a payment option.
- These payments may continue to be pushed down to the future Lightning Network (LN), a two-way payment channel, locking up time allowing almost free transactions. WooCommerce shows an active LN channel, although the LN solution is still in the testing phase in further development and testing.

Prospects for a new round of bitcoin growth
- Since bitcoin has risen 34% since the beginning of April, it has not improved its 21st position among the top 25 currencies, however, the bitcoin market capitalization remained high at $ 152 billion. before dropping back then.
- Typically, bitcoin will be purchased and then used as a means of trading for other codecs, which may help boost bitcoin prices in the current situation. According to CoinDesk, the price outlook for bitcoin will continue to increase, although it tends to decrease slightly. Even in the short term, the price is expected to test 200 MA of $ 9,737. If the price closes below the 10 day MA, this will signal the inactivity of the price increase.
- Electronic money orders are also the highest since March 2017, accounting for more than 92%, which may be a sign of a strong market.
- At the same time, adoption of virtual currency is starting to increase globally so new growth prospects in both short and medium term of bitcoin are perfectly possible. We can still believe in the stronger development of this currency in the future.

The true value of Bitcoin:
Up to now there are 11 million Bitcoins in circulation around the world. It is estimated that by 2140, the total amount of Bitcoin can reach a maximum of 21 million. The amount is so but the true value of Bitcoin is not everyone understands. Because there are many people mistakenly think Bitcoin is the amount of money in fiat currencies (USD, Euro, Yen, Pounds, VN dong ...). However, the real value of Bitcoin is not reflected in the price. It lies in usefulness, convenience. It's also where you want to get Bitcoins. No organization can intervene and control. So the real value should be reflected in the security in the purchase and payment.
Because the currency needs to fulfill three important functions: payment, accounting and value storage. But so far Bitcoin has not become a real currency. Because payment facilities are not easy to guarantee.

To avoid ICO scam:
1. Be careful never to admit
The first step for investors to undertake is to conduct in-depth research on a project. Infinite investment in ICO can bring huge profits in the distant future, but it also significantly increases the chances of investing in a fraudulent project. Unplanned ICOs must be avoided, as it is a minimum requirement for any serious project. If the company or project can not convince you of its application possibilities, you should not steal your wallet for them.
â.Avoid address spoofing
In many cases, we see people distributing fake Ethereum wallet addresses to participate in a pre-ICO algorithm. This mainly happens on Telegram, but Slack can also have similar problems. Never trust the address of an Ethereal wallet sent by someone you do not know on the internet. Do not ask for these addresses, because all you have to do is just a big donkey. Use the information provided formally and the address displayed on the legitimate ICO website.

It will be necessary for you to grow, to bring into full play the potential power you have, the block phone chain is very useful, they are very convenient device to have but my problem is that I find See them too clearly. For example if I want to keep bitcoin, I prefer to do it on a piece of paper even if you look at it

Bitcoin can not become a currency, it has been around for a long time, it has grown, but it has not reached the top.

Bitcoin needs a lot of power so you can maintain it, it's pretty high
