To my mind, we need projects connected with credit card for cryptocurrency. More and more people are interested in altcoins, but they don't know how to get them. Even if you know exchange to change fiat to Bitcoin or Eth and you invest them in ICOs, it's difficult to change altcoins ang get fiat. So we need a special card to pay for all goods and belongings everywhere. Of course, there are some ICOs that have already presented their cards, but Visa and MasterCards are so popular that it sounds impossible to creat something more well-known. I will there would be cryptocurrency cards and they will be easy to use.
This is actually a pretty cool idea, as some stores already accept to use BTC to pay, some other Altcoin may can too.
