I have a doge wallet, can I use it to collect litecoins? Or do I need to specifically get a litecoin wallet to receive payments for hashing? Thank you.
Any wallet is based on the particular set of cryptographic functions used for a single cryptocurrency. If you tried to send dogecoins to a litecoin wallet address, the transaction would not be valid because the dogecoin blockchain is only a record of dogecoin transactions and the litecoin blockchain is only a record of litecoin transactions.
