No matter how how good blockchain technology is put it in a financial model then it a whole different ball game. When buffett says cryptos will come to a bad ending in 5 years i think people have to sit up and take notice. And not just take the view that he does not understand the tech. he dont need to understand it for the simple fact they have gone up to fast. Make no mistake cryptos are in a bubble. How does the bubble burst hard to say it could carry on its rinse and repeat cycle. And we could have a long drawn out bubble that lasts a few years or a massive crackdown by governments making it illegal. Or banks just blocking your exits to cash out
