Sorry but the question is a bit confusing or I don't understand it.
Do you wish to trade using copy trading or bots?
Or just buy Bitcoins and invest for the long term?

If it is for daily trading, then both of them are actually helpful. Whether it will be more effective, it will also depend on your understanding of setting up and trading strategies with the help of both. If it's copy trading, make sure that you really find copy trading that is very suitable and accurate. But on the other hand, I think both copy trading and the help of bots are only tools, it doesn't mean that you will be safe and clam in trading activities with use one of them. You must first learn and understand what trading is and how strong mental control is. Because trading is high risk.

But if what you mean is investing in Bitcoin, especially for the long term, you don't need both. You just have to buy 4k of your Bitcoin money and save it in your personal wallet. Wait until the market turns good and set the price according to the target. Or if you want to fulfill it in the bullish era later, that would be even better.
