Blockchain is still an infant technology, and it appears to be stuck in the pioneering stage of innovation.

Every transaction adds a few hundred bytes to the blockchain, which accumulates over time to substantial file sizes that need to be stored in each node (miner’s) computer.

No major and profitable application of Blockchain yet emerged. Everything is “just a promise”. 

Blockchain is just “a solution in search of a problem.” If there are other easier solutions, why do we need Blockchain.
