some people will always try to discourage the newbie? You see them saying things like “Bitcoin trading is not for newbies”
I think you have misunderstood this sentence. The sentence ""Bitcoin trading is not for newbies"” true meaning is that newbie shouldn't invest until get knowledge of trading and I think this is very good advice for newbie so that he didn't lose from the start. Newbie should learn how the analysis work, how news affect the btc price and what to do in panic situation and most often newbies didn't aware of it and they start selling in lose when they saw panics selling in the market.
None of us here was born a professional trader, fact is that we all had to start from somewhere. We were all once a newbie, until we started learning and putting in the work.
Newbie should start from holding which is safe and no need of any trading knowledge. This forum is best place for learning but sometimes you will see some discouraging reply also but you have to check what's majority says and take cares about their advice. Newbie can start learning here but before learning if he start trading then high chances that he will loss all before learning.
