It didn't come from a cryptocurrency trading person, but probably now the person is trading in cryptocurrency currently because I think it's more exciting compared to the stock market because the stock market closes at a time, not 24 hours trading.
I have observed that also, it is not for cryptocurrency use. Is that link useful to cryptocurrency trading? My knowledge in trading is just very basic and i am planning to dig deeper on this that is why i am curious with that link baka hindi applicable sa crypto.
