As cryptocurrencies run through Blockchain system, those confirmations can vary per type of crypto, type of transaction (withdrawal & deposit), exchange and trading platforms. There are no minimums and maximums necessary to have your funds available after the request is made. As soon the funds are available in your wallet, they are suitable to be used.
For example, if you fund your wallet with BTC coins, in the transactions history located on your Dashboard, you can see how many confirmations it has at the moment, and this number can go as higher as 200/ 250 confirmations and up. However, this doesn’t mean we require all those confirmations before you can use the funds to trade or withdraw. Those confirmations don't imply they must reach a maximum until you can use it.
That’s only how Blockchain works. Once you can see the sum of cryptos inside your wallet, you can use them.
