Nobody. Should you send money, you send it. Period. No one can assist you, if you sent your funds to a scammer or whenever a hacker stole them from your PC.

2.) Pseudonymous: Neither transactions or accounts have been connected to real world identities. You receive Bitcoins on so-called speeches, which can be randomly seeming chains of around 30 characters. While it's typically possible to analyze the transaction flow, it's not necessarily feasible to connect the real world identity of users with these addresses. .

3.) Fast and global: Transaction is dispersed nearly instantly in the network and are confirmed in a couple of minutes. Since they happen in a global network of computers they are completely indifferent of your physical location. It doesnt matter if I send Bitcoin to my neighbour or to someone on the other side of the world. .

4.) Secure: Bitcoin funds are locked in a public key cryptography system. Only the owner of the private key can send cryptocurrency. Strong cryptography and also the magic of large numbers makes it impossible to break this strategy. A Bitcoin address is much more secure than Fort Knox.

5.) Permissionless: You dont need to ask anybody to use cryptocurrency. Its just a software that everybody can download for free. Once you installed it, you can receive and send Bitcoins or other cryptocurrencies. No one can prevent you. There is no gatekeeper.
