stock market is not safe either. if you have been in the market for some time, people are also losing money in stock market, its almost the same thing here in crypto you have to check the news and what is going on to the development of the project and to the team as well. if something happen to them or to the project the prices drops just as in the stock market.
Its true, I would rather choose trading cryptocurrency over stocks because when it comes to exchanges, stocks has large transaction fee compared to cryptocurrency exchanges. Another reasons is that, cryptocurrency exchanges has complete range of tools in trading like indicators and notifications for the users.
