How do you know which cryptocurrency my entered wallet information belongs to?

I will enter Dogecoin wallet information, but is 2 USD sufficient for this withdrawal transaction limit?

We review all wallet addresses submitted for withdrawal using https://blockchair.com

The type of cryptocurrency it reports is how we send the funds to you.

Also, DOGE is extremely expensive as are many other memecoins right now.  It costs on average a little over 11 DOGE to send the transaction.  That's about $1.12 - $1.20 right now.  If you request $2 as a withdrawal amount, most of it will go to the transaction fee.

You would do better requesting TRX, LTC or others that have lower fees.

Thanks
