Bitcoin is more secure today than before. It is getting safer day by day.

A 51% attack would require time because each block to go back needs 10 minutes to create another one. An attacker can't change consensus rules but can change the blocks themselves and while having spend a transaction, like sending to an exchange and selling, he can reverse this on the blockchain by finding the block and changing it with other transactions, or no transaction. But the more behind in block number this transaction is then the more time and energy it needs to be consumed.

Bitcoin hash rate is what makes the blockchain safe from attackers. Nobody can tamper the transactions because the blocks are not accessible unless someone spends hundreds of millions of dollars to reverse them and as said in this post in this case they will only be able to reverse a few transactions from the last blocks.

Bitcoin blood is what we need to talk about it, the more the miners the more will he the hashes generated, the hashes generated are the strength of the blockchain, if more hashes are generated then the stronger the blockchain. The miners are increasing year by year, this also makes the bitcoin blockchain to be secure than before.

Of course the bitcoin and all crypto currencies security in general are developing their security day by day, so that's why also scammers are continuing to develop their skills of attacking.

That is really cool. As we progress, more and more ways to improve security are created. But hackers are also becoming more and more smarter everyday and with china at the verge of producing the quantum computers for commercial use, i think it will also pose a threat to blockchain security because these computers are super fast and have the capacity to pernetrate blockchain network.

The percentage of protection in every company, institution or platform must increase over time, due to the experiences and exposure to theft operations that give experience in dealing with such cases. This is what blockchain takes advantage of, and thus becomes more secure over time.

[jackycrypto485 1055]

It is true, the greater the number of blocks in the Bitcoin blockchain, the more secure the network is. Attackers need 51% of the bitcoin's hash power in order to carry out their attack, which is very difficult at the moment and needs very huge money.

[LOLIA NAHHAS 339]

Yes, this is true, and that is based on extremely complex and accurate algorithms
The high security that Bitcoin provides to its clients over time increases its circulation and raises its value
What a genius that started it.

[kenan975 54]

In my own opinion, I see that the cryptocurrency Bitcoin is not as secure as required so far. The fluctuations in terms of its value and price in the market are still volatile despite the great complexity that occurred to it through the huge quantum network around the world.

Dear friends, Bitcoin is the best website in network marketing.Initially it was not considered secure.As time passed, its importance increased.Now the time is passing, the more it is becoming secure. 

[maarcoferrer 1096]

This is totally true and thanks to Cryptotalk because in many ways it makes it more secure with all the information it gives us. Before there was not so much security information regarding Bitcoin, that's why so many bad things happened, like losing wallet keys, that's why there are so many lost Bitcoins, but today security is more advanced and it is easier for us to get information about everything.

[Whited35 15285]

Of course, yes. This is the beauty of the distributed ledger technology like blockchain network for Bitcoin. More the connected nodes to produce hasrate, more secure Bitcoin network becomes. Really, it is impossible to the set of hackers to hack entire Bitcoin network as the huge computing power is required to reverse the work done by algorithm of Bitcoin blockchain. 

[joemcgwa 3227]

When many challenges happened to bitcoin such as scamming and hackings issues, there is how the bitcoin technology also learn from those challenges and knowing the best ways to improve the security.

I also now see responses without wording,the blockchain technology is developing more and more day by day, and with the development of the blockchain technology,It is something that simply can't be done and it would provide no profit if it is ever performed by someone.

[abohasnn9 2401]

My friend, since the end of 2020, Bitcoin has taken a wide spread trend and has become a currency that no one is afraid of, as it has turned into a central currency somewhat due to the adoption of PayPal Global Bank for it and the establishment of special portfolios within it and its adoption by depositing and loudly with it in a simple manner and in a central feature for central currencies Thank you very much

[SelimAbi 339]

I totally agree with you on this. Considering Bitcoin 5 years ago, it has improved itself a lot in terms of trust. As you said about security, they are improving day by day.

[Jacks52 351]

the conversion of currencies based on the blockchain technology,this is the secret to the security of the blockchain transfers.It is something that simply can't be done and it would provide no profit if it is ever performed by someone.

[habeb 139]

I agree with in terms of blocks and I think that Bitcoin will become more and more secure, but for how long? will Bitcoin stay forever or will governments eliminate it for fear of disruption of the global economy?

[Rozy 1918]

It is like a circle the higher Bitcoin price is the more people who want to buy it the more secure it will become and then the price will get even higher, and we see it right now, it is making new records everyday and more people are feeling like it is a secure investment and they want to buy it.

[Mir Hamza 2888]

Yes, I agree with you. As we can see that this time the price of bitcoin is also increasing because many people are investing on bitcoin and start their work here. Along with the man, we are also seeing that as the price of bitcoin increases, the security of bitcoin is also getting toughest. As earlier we used to hear that bitcoin used to work with many people today but now it is not at all because now scooty of bitcoin is getting harder day by day and scam bitcoin is very much. 

[David84 1191]

Maybe it is getting safer but the hackers are becoming more experienced and they use very advanced technologies to hack into people's accounts. Any online data is secured to certain degree, but no one can give you a one hundred percent guarantee, so it is better to choose the best exchange to deal with.

[Cleaner 2549]

Blockchain is currently providing very strong security to protect Bitcoin.  However, the bitcoin he uses will depend on how he protects the bitcoin.  If we keep Bitcoin in a good wallet, we can easily keep Bitcoin safe. However, it is not safe to keep Bitcoin on exchange sites.  Strong security is coming out day by day to keep Bitcoin safe

[teebasas 3018]

Bitcoin has been safe right from the beginning of its market because it is not a manual money transfer. Because of the right technologies, this happens and we can track our transactions at any time we need and anywhere.

[Moudr 513]

Hello, my friend. Indeed, the degrees of safety and confidentiality in cryptocurrencies are very high, and his passion is what made them very popular with major companies, and currently countries are trading in them.

[Hamza balouch 268]

Yea it is right btc value is increasing day by day and huge number of investors are investing in btc.Thats why we can say and trust btc is safe coin and we can invest in it.
