Cryptocurrencies are actually the future of monetary landscape.

Many companies, governments and banks are working on developing their own blockchain that will likely to be supported by some cryptocurrency. We will definitely gonna see many currencies from big names in future. But they might not be as decentralised as Bitcoin. Bitcoin being pseudonymous and decentralized store of value can be face changing currency. It gives financial independence to the people. As happened Zimbabwe and Venezuela where people due to high inflationary state currency, went into cryptocurrencies.
