This is usually the first practical question people ask once they understand what copy trading is: how much do I actually need to open an account? The honest answer is that it depends — but there are a few useful ways to think about it.
There's no universal minimum
Minimum deposits are set by the broker and account type, not by copy trading itself. Some accounts open with a few hundred dollars, others require more. Rather than chasing a specific number you saw somewhere, check the current minimum for the specific account type you're considering.
Why account size affects risk more than opportunity
A bigger account doesn't make a strategy perform better — the strategy's results (win rate, drawdown, consistency) are the same percentage-wise regardless of account size. What account size actually changes is how meaningful the dollar swings feel to you personally, and how much room you have to withstand a losing streak without it affecting money you need elsewhere.
A simple way to think about sizing
A reasonable starting principle: only allocate money you could fully lose without it affecting your day-to-day finances. Copy trading inherits the drawdowns of the underlying strategy along with the gains, so sizing your account around your own risk tolerance — not around a number that sounded impressive — tends to lead to better decisions later.
Growing from a smaller starting point
Starting smaller and adding funds later, once you've watched the strategy perform over weeks or months on a live, verified account, is a reasonable way to build confidence before committing more. There's no rule that says you have to decide your final account size on day one.
The bottom line
There's no single right number to start with — only a right number for your own finances and risk tolerance. Check the actual minimum for the account type you're considering, size it around money you can afford to lose, and use a verified track record to judge the strategy on its own terms rather than on how much you've deposited.
