In my opinion for all the traders and newcomers swing trading and long term trading is best for gain profits with less risk because i mostly see that many traders become holders after some lose and many holders become traders after some profits but these two styles need a high study and experience before jumping into the market .
Nothing is safe in Cryptocurrency trading, everything still has a high risk, especially for traders who are new and don't know some of the cryptocurrency networks, so learning everything first and after that buying a coin with potential is better than having to buy a lot trash tokens that only make a lot of losses.
