Thanks guys,
I reset the Jaxx cache a few times. Now I see my BTC in my wallet.
Though, I don’t know yet why it didn’t get confirmed.
was it because of miners and this Segwit2x mess?
Any way, maybe this issue or case proves that blockchain technolology is 100% safe, you never lose your money. In Fiat transaction, if you made a mistake, it’s up to the receiver to refund you the money, which is not the case with blockchain.
So, remains the question, why it didn’t get confirmation?
Since you checked the "website" and the transaction wasn't logged on the "website", (I'm guessing the website is some kind of block explorer. I don't use the Jaxx Wallet, so not 100% certan what website you are talking about.) I am guessing that your transaction was never relayed to the Bitcoin Network. This can be caused for a multitude of reasons. Either your phone carrier dropped the signal, your internet connectivity has an issue, or your Iphone had a software or hardware glitch. If your transaction did appear on the "website" but it is still unconfirmed, than it is because your transaction has not been included in a block, yet. The bitcoin network has been congested today.
Furthermore, the blockchain technology is not 100% safe. If you end up sending your BTC to the wrong address, you most probably will never get your BTC back. The reason is because if you make this error, the chances are 99.99xxx..% likely that no one has the private key to the erroneous address. Therefore, no one can refund your money. Also, there is malware out there that changes the clipboard information, so you end up pasting the BTC address of the hacker, not the address that you copied. (Scanning A QR code may be a safer. I'm not aware of malware that can somehow cause trouble with that. But the hackers these days are getting so ingenious.) Always double check the BTC address before you hit send.
