transaction's limits I'm new about this market and I don't know if there's some limits about the transactions on the copay wallet. I think to use this wallet for personal and business transactions.
Someone can answer me if I can receive on the wallet several transactions and if there's some limits about btc I can receive?
Tks
Coins are sent to addresses in a globally distributed ledger, not to wallets. The Bitcoin network does not “know” what wallet-software you are using to manage your addresses, and it cannot prevent people from sending coins to addresses that you own. So, the short answer to your question is “No limits.”

One thing that might delay a transaction would be if the payee set the transaction fee too low. Miners, being economically rational, tend to validate transaction sooner if the fees are higher. If the fee is too low, then the coins may get returned to the sender without ever being credited to the recipient. But this has nothing to do with the recipient's wallet-software, since fees are set by the sender.
