FinTech banks are disrupting traditional banks, but what if you want to move your money into a cryptocurrency asset? If you sweep your funds into a cryptocurrency account, what cryptocurrency are you going to use to hold your funds?
If you pick Bitcoin, Ethereum, or any other top-ranked alt-coin, you’ll be exposed to extreme levels of volatility, compared to other assets.
And what if you need to move fast? Even if you’ve already set up your account, how are you going to fund it? If you use a debit or credit card, then, generally, you’ll have to pay a high fee, and you won’t be able to move that much fiat currency without your bank raising an eyebrow. What about a bank transfer? Yes, the fees are much lower than using a debit or credit card, but usually, a bank transfer takes a few days to clear into a cryptocurrency account — you could be waiting three to five days before your funds are available.
Remember the British pound to Australian dollar example earlier, if you wanted to take advantage of that situation in real-time, back in 2001, you had to have your cash ready to move — your account needed to be fully funded, ready for you to pull the trigger.
