Investment is usually for a long term in contrast to trading where you buy and sell in short duration. Trading is not for everyone rather only experienced people who have spent their time and effort learning the trading can handle it with perfection up to some extent. Investment is secure and less risky if you have the patience to wait for longer duration. For newcomers it's advisable to stay away from trading because it can give them heavy losses, the best way to move forward in crypto for newcomers is to invest for long duration.
How then can newbies become traders if you advise them to stay away from trading? I would say that newbies should trade with small amounts of money when they just start practicing trading, and be prepared for the fact that this money will be lost, in this way he will gain experience. By the way, I could not find any precise statistical data where I could check how many traders are successful, I think it is very difficult to calculate, but in reality there are very few successful traders, this is almost an indisputable fact.
That is the thing newbies should understand so they can practicing trading and improve their skill by learning more. They will understand that many traders will not profitable if they don't want to learn and only expect a signal from others. By suggesting them to try with a small amounts of money will open their eyes that trading need skill to profit so if they can not spend time to learn, it is better they don't have to trade. They have a choice but yes, that will depend on themselves so they want to improve their skill in trading.
