The positive side of cryptocurrency Peer to Peer Transfe.I can send you money directly without any middleman. It is a positive thing. But it can be a negative thing because if I send the money directly. In that case, if you have any illegal intentions or if I have any terrible bad intentions, then I can take the money directly from you. If there is a bank in the middle you can get your money back in many ways. When you send money directly, there is no possibility of getting this money back. This is why hackers say bad things are happening.Bitcoin is now the most popular thing or cryptocurrency in general among people in the criminal world. If it is a peer-to-peer transaction through cryptocurrency, it is a big deal.
Bitcoin network is secure, it is almost impossible for a hacker to hack the network because of the networks high hashrate. If one fell victim to a hacker, it is his own fault and not the system.
Aside from that, unless a person falls victim to a scammer and is swindled into sending him Bitcoin, no one can get his Bitcoin as long as it is securely stored in his non-custodial wallet.
Once sent, there is no way to get it back and it is very difficult to trace.
Not true, once sent as long as the transaction is not confirmed, anyone can cancel it through double spending and sending it back to the owner's wallet. Remember for a transaction to be successful, it needs to be confirmed by the network. Anyone can cancel the sent transaction as long as the transaction is still unconfirmed.
You can see which account is going from which account. But it is very difficult to find out who is the owner of that account. This is a negative aspect of Bitcoin.
I think this is the strongest feature of Bitcoin, by not knowing the identity of the sender, it help people protect their privacy. Having privacy means people are safe from malicious prying eyes and is kept away from people who has bad intentions.
