There's a big difference between manual trading and using trading bot. Manual trading requires a lot of time to lear things like Analysing the market, checking how market conditions evolve, Evaluating the impact of the market moves on the profit and loss of his positions and etc... In short, you need a lot of time to do all that while the trading bot just do it straight away because they're already programmed to do it.

If you want to trade bigger coins like BTC I think it'd be safer to use a trading bot, besides using a tool like that gives advantages like no normal traders can do like how they don't sleep, how they're fast, how smart they are and how they trade without emotions or feelings.

BUT, It’s probably impossible to beat a professional trader. Experience plays a crucial role in managing stress and developing an advanced trading system. Sadly, traders that reach these high level of proficiency are very few. Only a very low percentage out of millions of people trading cryptocurrencies or traditional assets every day are professional.
