Think about it yourself, why would any expert who can spend their time making good profit from trading waste that time creating trading signals every day or every hour to let others know what to do?
The reality is that those newbies who can't make profit from trading start selling signals to other newbies so that they can make money from that instead of trading themselves!
Actually accumulated over 2000 BTC back when... sold it for what it was worth at the time (under 1$) as I needed to pay my rent. never did HODL, the biggest mistake of my life, and still makes me sick to think about it.
Selling bitcoin is not a mistake, selling all the bitcoin you have is.
