Bitcoin is not only a vessel to store value but it's also really useful in the remittance industry. I can send 100,000$ paying a mere 4$ in fees with Bitcoin while it would cost me 3000$ with PayPal and I'd take some risk to do the paypal transaction while doing the same thing from a traditional bank would cost some money,time & would probably raise questions.
We can also transact using bitcoin anonymously, so our identity is secure. instead of going to bank to process payment or to send money. We can do that using bitcoin online.
