If you are just new in crypto, better to learn first and gather some knowledge about trading. Also I don't think if there is best technical indicator to be use in trading.For me if you know how to analyse and understand the graph and price movement, it can be a great help for you in doing trade. Also spend time to search good altcoins to trade.
Well said. For new comers in crypto it is better to learn first and think about earning later. Nowadays a lot of Learning material is available on Youtube about Fundamental and Technical analysis of crypto market and it is free of cost. History of trading vindicates that most successful Traders in stocks, Forex and crypto are those who use Technical Indicators and have good Analytical skills which is definitely helpful to make entry or exit in trade at right time.
