I just seen this thread. You ask, "Do we need blockchain technology?", Well, I guess we need it. We need transparency, esspecially in my country, I hate corrupt officials. Yes, like that, I hope blockchain technology will be implemented in goverment and revolutinize my country. Just my opinion..
Just like your said, "too many ICO and shitcoins", I aggree with you mate, so that's why in investment I always choose the great project and backed in real product like Robotina.
