The functionality of Matbi is truly impressive, especially among many competitors. It serves as a wallet, an exchange, and a trading platform all in one, with an acceptable level of security. The comfort of use raises no questions: both the desktop and mobile versions are executed at a high level. Overall, if you plan to buy relatively popular coins, this is an excellent choice. However, for those looking for something rare, there may be issues with finding it. On the negative side, I would note that the verification process turned out to be quite complicated—I had to spend a lot of time taking "quality" selfies.
