Which is better to invest in copy trading or bot
And is there any other alternatives
I have 4k btc to invest
Isn't copy trading and a bot almost the same thing? If you are going to copy trade, you are going to use a bot anyway.
But yeah, none of them is the best option to invest in. You should learn how to trade by yourself. Those copy trading can never guarantee you profit and one mistake, you end up losing everything. And I am not sure what you mean by investing in a bot. A bot with trading strategies? Still has no guarantee to give you profit and the bot might mess up leaving you with nothing. Also, don't trust third party bots. You never know what those bots can do. The next day you will see that you have nothing on your account and everything stolen.
