A deposit into an existing bundle is divided according to the target distribution of the bundle. If you have not adjusted the target distribution (FAQ – Manage Bundle – What is target distribution) the payment will be distributed as follows:

Big 3: 45% Bitcoin (BTC), 30% Ethereum (ETH) and 25% Ripple (XRP)

Top 30, DeFi and Penny Stock : equal distribution across all coins in the bundle

You can change the target distribution prior to the additional investment if you like. Maybe you want to invest more in one or two coins in the bundle. After the investment, remember to change the target distribution back because automatic and manual balancing also use the target distribution and then you may inadvertently sell all other coins for these one or two coins.
