  The problem of investing into a cryptocurrency market requires good
understanding of the processes that regulate the price of the currency. In this
paper we offer a view of a cryptocurrency market as an environment for
realization of a self-organized speculative scheme that results in a formation
of a characteristic price bubble as a transient phenomenon. We use microscale,
agent-based models to simulate the system behavior and derive macroscale ODE
models to estimate such parameters as the return rate and the market value of
investments. We provide the formula for the total risk of the system as a sum
of two independent components, one being characteristic of the price bubble and
the other of the investor behavior.
