Hello,
This is Cryptopia's answer:
Hi,
Our wallet team have reviewed ARCO, and have determined 200 blocks is only ~4 hours, based on ARCO being a SCRYPT coin with a 64s block time.
So they feel the current 200 confirmations is a reasonable compromise of security and convenience.
Please let us know if you believe that information is incorrect, otherwise our ARCO deposit confirmations will not be changed.
Apologies, this is probably not the positive answer you hoped for.
I got this answer from Cryptopia Support:
Thank you for contacting Cryptopia support. Each coin requires a number of confirmations before a transaction is credited and available in your balance, this is a variable amount based on the strength and security of that coin's network. You can check the number of confirmations required for each coin on the CoinInfo page under Settings which this direct link will take you to:
