The very best thing is to identify with a reputable crypto exchange with track record of achievement to register and then begin to invest in knowledge to learn about the coins that can turn the table by subscribing to several genuine crypto newsletters like cointelegraph bitcoin news or join crypto forum like remitano to get acquainted with terminologies, technologies, Metric Analysis, Expert opinion etc...when the beginner is now duly informed to be aware of the relevant knowledge particularly on risks related to cryptocurrency as well as best practices to adopt as personal approaches for investment, he can make informed investment decision thereafter but it should not be by putting the cart before the horse!!
