Bitcoin is not anonymous and can not provide the same level of privacy as cash. The use of Bitcoin requires extensive public listing. There are various mechanisms to protect user privacy, and more are being developed. Bitcoin can not be more anonymous than cash and will not complicate the procurement of criminal investigations when necessary.

Bitcoin has value because it is as valuable as money. Bitcoin has the properties of money (durable, concise, exchangeable, rare, divisible, and recognizable) based on mathematical formulas rather than based on physical form (such as gold and silver) or trust in the central (such as fiat currency). In short, Bitcoin is supported by math. With these attributes, all that is required of money to have an exchange rate is trust and acceptance. In the case of Bitcoin, this condition can be measured by the growth of users, sellers and early users. Like other currencies, the value of bitcoin comes only from people who are willing to accept it as a means of payment.

Rapid price increases are not always a bubble phenomenon. An artificial overdelivery that will lead to a drastic reduction in correction is a bubble phenomenon. The choice based on human behavior by hundreds of thousands of market participants is the cause of bitcoin price changes so the market is trying to find the price. The reasons for behavior change may include loss of confidence in Bitcoin, the big difference between value and price is not based on the basis of Bitcoin's economy, an increase in press coverage that spawns speculative demand, fear of uncertainty, and excessive antiquity and greed.

Most trust in Bitcoin comes from the fact that Bitcoin does not require any trust at all. Bitcoin is entirely open-source and decentralized. This means everyone has access to the entire source code at any time. All the developers in the world can verify exactly how Bitcoin works. All published transactions and bitcoins can be viewed in a transparent and real-time manner by anyone. All payments can be made without being dependent on third parties and the entire system is protected by a peer-reviewed cryptography algorithm as used in online banking. No organization or individual can control Bitcoin, and the network remains secure even though not all users can be trusted.

Bitcoin is a consensus network that enables new payment systems and money that are entirely digital. Bitcoin is the first decentralized peer-to-peer payment network that is fully controlled by its users without central or intermediary authority. From the user's point of view, Bitcoin is similar to cash in the internet world. Bitcoin can also be seen as the most prominent record-keeping system currently available.

If you are serious about investing in Bitcoin, you should set aside some of your salary to buy a digital currency. Here's how to accumulate a lot of BTC over time without one big spend. Many Bitcoin wallet sites (eg Coinbase) offer the option to set regular withdrawals to buy BTC. The trick, you specify a certain amount of money, and this amount is withdrawn from your account in regular intervals and used to buy BTC automatically.

How to secure Bitcoin, as follows:
1. As a Developer get used to listen to feedback from users to minimize the possibility of Code Error (Faulty Code) as happened in DAO Attack.
2. Staying relaxed and cool when getting information from emails or other messages that require you to do something, emotion and hurry that is being used by the hackers.
3. In storing the cryptocurrency assets you always take note and note: 1. Where and how do you keep private keys? How to preventive measures if your place to store lost / damaged? Have some digital backups and wallets in the form of hardware or printed wallet.

In this case, there are some weaknesses in BTC, among others,
1. Level of acceptance - Many people are still unaware of the existence of Bitcoin. Every day, more and more businesses are receiving bitcoin because they want to profit from bitcoin usage, but still the user list is still small and needs to grow to benefit from network effects.
2. Volatility - The total value of the bitcoin in circulation and the number of businesses using Bitcoin is still very small compared to what it should be. Therefore, small events, trade, or business activities can significantly affect bitcoin prices. In theory, this volatility will decrease as the market and technology of Bitcoin develop. Previously there was never any currency created by itself, so it is very difficult to imagine what developments will happen next.
3. Ongoing development - Bitcoin software is still in beta with many incomplete features that are still actively developed. New devices, features and services are being developed to make Bitcoin more secure and accessible to the public. Some of these developments are still not ready for everyone. Most Bitcoin businesses are still new and have not offered insurance. In general, Bitcoin is still in the process of growing up.
