Yes I really agree on this one right now a lot of people has been started when bull market runs really attracted to cryptocurrency because they only knew that they can make easy money even without basic knowledge and when the bear market started they are panicking and thinking that cryptocurrency has come to end. Remember always do your own search in everything before you invest your money.
