This Morning "A friend of Mine" was trying to buy Ethereum in order to buy some altcoins. When he/she tried to purchase they got an invalid card error. They called their bank (you can probably guess which one by the picture) and Coinbase was on the "Fraud" list. They had to go through 30 mins to buy the Ethereum.
If this isn't a reason why you should invest in crypto-currencies, I don't know what is.
