This is certainly the only thing that could be done by mere traders and investors. Developers could work on improving some proposal as more of them arises. But for the traders and investors alike we moving towards decentralized platforms could reduce the need of centralized ones which are the areas been hit by the government ones they are after bitcoin and decentralization. The government intolerance to the technology is the biggest threat currently been faced by the technology, and as more people hold bitcoin on centralized platforms it gives them more liquidity and popularity and therefor making decentralization looking more unrealistic.
The other thing that could hinder bitcoin in the future is the treatment of Altcoins. The more Alticoins are been created and more people turn attention to them, scammers will continue to steal peoples funds through it and could only discourage potential investors as they would classify even bitcoin part of them, which will only hinder the mass adoption of bitcoin which will be key to any future saga. Bitcoin should also be treated strictly as an alternative currency.
