Thank you all! I will most likely be using BC then. Sounds pretty safe and anonymous.
I will look into those other websites for another wallet.
Here is a full list of wallets out there :
https://bitcoin.org/en/choose-your-wallet For Desktop wallets I'd suggest : Bitcoin Core , Electrum , Multibit HD
for Android : Mycelium
for iOS : I'am not sure because I'am speaking for an experience and I never tested wallets on iOS device .
Stay away from Web wallets because they are the less safe . the safer are Paper wallet (free) and Hardware wallet which will cost your money . Paper wallet are mostly for receiving and not for sending because it will be a simple paper printed where there is Public adress + private key .
I checked both of these: "Bitcoin Core , Electrum"
The first wants to download 20GB of data into my computer. The second also seems to be some kind of software installation.
I just want to send some money to someone. That is all I want to do.
I can install software if thats what I have to do. But I thought I could send people money using a website that asks for my bank account/credit card like Paypal. That is fine with me.
What website should I use? I can use multiple websites if needed.
Well that what Bitcoin client is , it's an application that helps you receive and send Bitcoins . I don't suggest you to use Online website to hold your coins otherwise you may get hacked .
The file that Bitcoin Core is downloading is the Blockchain file that blockchain.info (and other block explorer website ) reads , if you want something easier then you could use Electrum as I said , there is "Receive" tab where you have your receiving adresses , you give them to someone and he send you the BTC . that's it .
and Personally I don't think there is no such at thing to send BTC using Paypal & Credit card . Unless you buy Bitcoins using those methods then send the Bitocoins . there is Virwox.com to do that
