There is no limit on the number of coins you can store on D'CENT Wallet because wallet addresses (accounts) exist on the blockchain network.
The following are the criteria for creating wallet addresses (accounts):
If you use a Biometric Wallet, you can create and manage up to 80 coin accounts.
(Ex, 40 Bitcoin accounts + 20 Ethereum accounts + 20 Ripple accounts, etc.)
You can also create new accounts from existing accounts after transactions have occurred on those accounts.
