I think it will become the new standard within the next 5 years. I already see a lot of digital goods venders accepting it nowadays.
Bitcoins can never be standardized in real market.Everyone knows its drawbacks.
That's why Big guns like google,facebook doesn't take much interest in cryptocurrencies.All of them are waiting to see where it goes.
I don't think big guns are quite afraid of investing into cryptos. They are still carefully monitoring the ecosystem and can anytime take a big step into it. We have already seen that companies like Microsoft and some other big names have started to accept bitcoin. Other companies won't stay behind, bitcoin has a huge potential and anytime can be the future of money system.
Honestly speaking bitcoins can be the world's future money system but the sadest thing is that it can never replace a major currency and it would be always used as a secondary currency, if bitcoins hits the mainstream than it would surely be the future money system and the mainstream adoption would play a key role in the success or failure of bitcoins.
