The more i read about Rootstock smart-contracts, the more i realize that ETH days are numbered. Those guys at Rootstock labs will making a next generation improved version of smart-contracts that be realesed around the end of this year and will smash ETH into the ground.
Remember this; everything that will be build on top of Bitcoins Blockchain will crush all competitors.
What if before rootstock is released someone else releases something with smarter smart contracts than rootstock's smarter smart contracts than ethereum's smart contracts?
