Digix sounds exactly like Goldmoney a.k.a BitGold.
I originally wanted to invested in Bitcoin last year but was turned off by the fact it was not backed by anything. Then I found out about Goldmoney about a year ago and was so impressed that I joined and was very happy until I kept doing my Homework and research.... There's nothing wrong with Digix or Goldmoney or anything like this but if you truly value your money you will soon see why this technology will be like pets.com
The reason no one jumps into Bitcoin, is because it is not backed by anything... like fiat. So the only natural choice is gold and silver... but as we all know these are only hard assets... So at first an idea like Goldmoney sounds amazing! Holding your real money (gold) and using the blockchain, best of both worlds...
Thing is, the whole point to holding a Bitcoin or an actual silver coin is the fact that no one stands in between you and your asset. So therefore even though Digix or goldmoney sound like a great idea they are not. When the turd hits the fan, whoever is holding your gold also has mouths to feed, and they wont think twice of taking the gold of someone they've never even met before, knowing full well that your claim will go in the same file as those putting in their respective claims once the banks liquidate their funds.
In fact if you think Bitcoin is slow, these are even slower and have to interact with the banking system. But you can hold/buy/sell bitcoin or a silver coin and remain anonymous. Huge difference.
If the whole system goes down, we have gold and silver to hold us until the system comes back up. if it doesn't go down, then we have bitcoin and ethereum. But if you think that some corporation is going to actually hold on to your "gold" while the financial system is rebooting then you must be smoking some really good pcp lol
In my humble opinion one should acquire physical gold and silver as insurance, as a real 401k, which can skyrocket in price tomorrow or in a decade.
If you want to invest in the future and be part of a revolution that will change the world far greater than the internet ever did, then invest and start using bitcoin. Bitcoin will be the "dollar" of the future. So buy now before it's too late.
The point is i made this discovery all by myself by actually using the technology myself. The reason I took everything out of goldmoney and put it into bitcoin, was because not only is it faster and easier to to use my Bitpay card, But i quickly realized that bitcoin is just a replacement for fiat. It is not gold, or silver, or even the actual blockchain. But what it is, is a fungible store of value. Bitcoin will destroy the banking system, just like youtube destroyed cable, and so on....
So to sum it all up have Gold, Silver, Bitcoin, and Ethereum. They will never fail you.
As for every other cryptocurrency just invest in what you actually believe in, that way if it fails you wont feel so bad, but if it succeeds then you can truly reap the rewards. Any other currency, ICO, or token after that is literally a gamble, don't expect to beat the casino.
Hope this information was useful. We are living in some amazing times, and we should all be constantly learning from each other, and continuously expand our minds with constant knowledge from all sides. We can become millionaires or lose it all with just the click of a mouse....
Good luck out there everyone!
