i need to know are there any trusted free wallets where i can store my BTC ? and can i for example have my OWN wallet instead of relying on third parties to keep my BTC ?...
Also what is the most reliable and trusted BTC trading website ? and is is advised to use that service as your main wallet or should i store my BTC somewhere more secure ?..
thanks,
You should use your
own wallet to store your Bitcoin. Storing Bitcoin on an exchange is generally a bad idea. Remember, if you don't own the private key of an address containing some Bitcoin, you don't own those Bitcoin. By storing BTC in an exchange, you gave exchanger control over your Bitcoin. Those exchangers might run away, hold and refusing your withdrawal request for some reasons, etc. There have been numerous unfortunate events from exchanger, MtGox hack/insolubility, Bitfinex hacking, and numerous account freezing and a lot more.
You can find recommended wallets list here:
https://bitcoin.org/en/choose-your-walletI personally would recommend Electrum for your PC wallet and Mycelium for Android/iOS. If you have some money, buy a hardware wallet like Trezor or Ledger instead, especially if you're planning to hold a large amount of Bitcoin.
OK TBH electrum sounds like the best option, but what if say the website goes down does that mean ill lose my BTC ?!
And can i sync my BTC between my electrum windows app and android ?? And does it support windows 8.1 or what ??!...
No, Electrum is not a web wallet service. It is a native computer software. By the way, ownership of Bitcoin is not related to what wallet you are using, instead it is tied to address(public key) and private key. As long as you store your Bitcoin in an address and you keep that address private key safe, your BTC should also be safe.
Electrum doesn't have Android apps yet AFAIK. But you can import your address private key into more than wallet, i.e into your Electrum in computer and Mycelium on Android. Both wallet will synchronize automatically as long as you're connected to internet.
