Bitcoin isn't a currency. A currency is a liquid asset that can be exchanged for physical goods and services. Unless you have a hearty coke habit, bitcoin is a security to you (the investor). The price is driven by 100% demand. The nature of bitcoin's structure causes this you can't "ease" bitcoin. A security with pure speculative value (read: a stock without a company) is doomed to be a bubble in the short term and worthless in the long term. Look at how it moved 20-30% in 12 hours on LOW VOLUME. The only thing that could establish bitcoin as an actual "currency" is if businesses started accepting it as payment in a widespread manner, with the shadowy past and clear pump/dump history, good luck with that.

Whether Bitcoin succeeds or not is not based on someone's opinions.
Bitcoin's success is based on whether the users of a such system manage to build up infrastructures, markets, softwares, hardwares for it.
