Bitcoin security is a topic of debate on a daily basis, and with more and more mainstream attention focusing on Bitcoin’s “flaws” and “vulnerabilities”, security measures need to be tightened even more. Especially when it comes to creating an easy-to-use, yet secure Bitcoin wallet to store your bitcoins, there are still plenty of avenues to explore. CoolWallet is trying their spin on this concept, as their IndieGogo campaign is generating a nice buzz in the world of both crypto and mainstream media.

Yes, it is credit card size.
But we can say it is cigarette pack size too.

"CoolBitx is making a hardware wallet that will store bitcoins securely offline", ok that is a fact.
But I think there will be much more cold storages, made by many companys.
Small usb with fingerprint key maybe?
Usb with size like mostly used as Bluetooth notebook adapters (tiny)?
Credit card size is not realy practical and not smallest.
Safety is on the first place.

I think the Mycelium Bitcoincard will be better if they ever release it!

There will be many secure wallets popping up in the near future. I think some of them do need to add even better security features though for peace of mind. USB sized is a plus as well and I don't think they need to be any bigger.
