I've been studying the underlying software architecture of bitcoin since spring this year and reading white paper proposals of projects like Cicada DDD, Iota, EOS...

One of the biggest problems with bitcoin is usability and along side it the centralized exchanges which now function to slow down the equity drain from national fiat into crypto. Decentralized exchanges still haven't solved the problem of liquidity.

For this evolution to really take off, it will require more businesses like mine (I'm CEO of my own software company) to start using bitcoin/crypto for payment. I've already started down this path.
