You say Cryptopia has come to life, you can make a deposit, everything is fine, but everything is not as you say. I made a transfer of coin 1337 from the CoinExchange to the of cryptopia. But there is still no money. It's been two days

. What to do?

How to return money back?
Have you checked the tx info you were given by coinexchange to make sure it is valid? If your coins show confirmations in the block explorer contact cryptopia support, if not, contact coinexchange support, it is not a problem with the coin, it is a problem with an exchange.
