That's called "copy trading", which has been around for decades.

If there's no connection between you and the trade you're copying, there's nothing you can be charged with. Normally there's a natural latency between the "signal" trade (i.e. the trade to copy), and the copy trade, which obviously can alter the profitability. This latency can range from sub-seconds if there's some public ledger, to days/weeks/months if the info is due to disclosure. Obviously when it comes to crypto and public ledgers, we're on the former.

But as soon as you place such trades based on insider trading, that's insider trading.
