Let's wait for cryptos baked by real assets like the soon to come Holo Fuel (actually represented by Ethereum based HOT). Holo Fuel, operating through Holochain (http://holochain.org), will represent available distributed computing power. This means a real asset for a real economy, in a mutual credit form. Check http://holo.host. More currencies like Holo Fuel will come. They will represent real assets, like gold, or copper, or wheat, or carbon emission, or working power, etc. These new currencies based on holochain framework may likely become a game changer and may push the Bitcoin in the 'old world' (let's not forget that we should call today's cryptos 'fiat' currencies too, like legal tender, as we give them value out of thin air).
