What is the blockchain

The block chain is the technology behind bitcoin that acts at the same time as a database and system backup. As we have just seen, in a traditional financial system, any transaction is entrusted to a third person (bank, credit card ...). With block technology, users are the ones who do it.

The blockchain is like a great book of digital events (transactions in the case of Bitcoin) shared and distributed among many people. It can only be updated based on the consensus of the majority of users and, once updated, the information cannot be deleted.

In this sense, each blockchain that is added contains verifiable information of all the transactions that have been carried out in the history of bitcoin.

To buy bitcoins, just go to one of the bitcoin trading platforms. Those who already invest in the stock market will find its operation similar, although somewhat different from that of a broker.

These platforms are called bitcoin wallets and it is where the virtual currencies are stored. There are different types of bitcoin wallets depending on issues such as security and usability.

The former are bitcoin wallets for PC, which you can download as a program for your computer. The second are the online virtual currency wallets, which can be for mobile phones or computers, it does not matter. The latter are the safest and are the hardware wallets.

Which bitcoin wallet to choose

The market for bitcoin wallets is broad. The Bitcoin Wallet you choose will depend on the use you want to make and the number of bitcoins you have associated with your user address. Virtual wallets are suitable for small amounts because they are much faster to operate. Rather, they are not as recommended for storing large quantities.

Among the best known wallets is Coinbase , very easy to use and intuitive, but it will also charge significant commissions every time you buy, sell or transfer bitcoins. Also, being a platform or exchanger, the security of your bitcoins will depend on their encryption and not on what you do. That is, you will be including a third party that is the one that will have all the data of your bitcoins.
