I took a look at the Roqqu site and it looks more like an exchange that lets you buy and sell a few specific cryptocurrencies :
Dash does not seem to be supported, when looking at the crypto currencies they support.
They seem to support only the following crypto currencies : BTC - ETH - USDT - XRP - EOS -
TRON - BNB - HIVE - STEEM
In this thread OP provided two links to images, one leads to a Dash wallet balance and one leads to a TRX (Tron) transaction.
OP needs to contact Roqqu directly and look for a way to withdrawal his purchased / received coins (TRX or DASH) to a wallet address that OP controls.
If it is Dash, then use an officially supported Dash wallet from dash.org and withdrawal from Roqqu to that new personally controlled and officially supported Dash wallet address.
If it is TRX, then use an officially supported TRX wallet from Tron's official site and withdrawal from Roqqu to that new personally controlled and officially supported Tron wallet address.
I have to say though that at this point it is unclear to me why OP transferred a small amount of dash from Binance (that fully supports Dash) to Roqqu (that does not seem to support Dash).
These are the places that lets you trade (buy / sell) Dash :
A traditional cryptocurrency exchange works much the same as a stock exchange, with buyers and sellers trading based on the current market price of the cryptocurrency.
