Blockchain is what is trending right now despite the fact that Government is giving us ash moment but believe me that next more years to come Blockchain will take over everything, industries oil companies and many more, but right now everything seems hard..
I think that it is not needed everywhere. Because of the wave of the hype for crypto-currencies, the blockchain is trying to be attributed everywhere wherever possible, but is it necessary? Why do oil companies or timber mills need blockchain? It seems to me that ICOs that run with similar ideas are uniquely a scam.
