Is it really shit advice? Selling at resistance and buying back at support has proved very profitable over the last three years. Just saying....
yes, because newcomers won't know who to listen to or what to believe. they'll walk straight into wherever the professional traders want them to.
you see the same old thing every day on r/bitcoin and elsewhere. people try to badly time the market and end up poorer. if you know more then great. people who don't have years of experience should take the long road instead by cost averaging and selling when they reach their target.
i am absolutely sure there are people like this who bought at $2700 and will sell when it gets to $1500 again. they shouldn't have gotten involved at either price.
