Hi
I`m considering using bitcoin but I heard some things that make me think otherwise and I want to know a few things before starting!
I`m getting money on paypal and I`d like to transfer this money to bitcoin in order to transfer it to Neteller:
1. Are there always people who will buy my money from paypal for bitcoins?
2. Are there always people who will buy bitcoins for Neteller?
There will usually be many people who are willing to exchange paypal or neteller for Bitcoin. However, in most cases, you need to be trusted because PayPal and Neteller are reversible. Also, you will usually end up paying a high premium due to the risk that the seller takes by exchanging Bitcoin for something reversible.
3. I heard people hack wallets - What is the best way to avoid it and how safe is it?
It is actually hard to hack a wallet. Never use a web wallet; many times those websites have poor security practices and end up being hacked and the Bitcoin stolen, or they run away with your Bitcoin, or the service is just plain bad (e.g. blockchain.info).
If you have a hot wallet (a wallet that is on a computer connected to an internet), make sure that you keep the wallet software up to date, keep your operating system up to date, have an antivirus software, and use different strong passwords for your computer and your wallet. Always encrypt your wallet.
If you have a cold wallet (a wallet on a computer not connected to the internet, recommended), make sure that the computer you have the cold wallet on is clean of any viruses, and that you plan on never connecting that computer to the internet ever again.
Also make periodic backups and keep them in a secure, offline place.
