Guys, what's your view on cryptocurrency cards (like credit cards, I mean)? Is it convenient or useless? If someone has an experience of using them, would be glad if you share!
As a bounty hunter, there are many ICO projects that provide also a crypto currency cards and as far as I know most of them are have a successfully project. But for now I really not have experienced to used crypto currency cards.
your definition of "successful" is flawed which is why you think they are successful.
success doesn't mean raising a lot of money and having a big hyped up market where people trade the useless token they created. success means if they truly create a useful product that people actually use in the real world and most importantly it means if they actually have a company and it survives in the long run.
