Bitcoin wallet address format representation I want to send coins from my ether wallet to another bitcoin wallet that I have got. 
I entered my bitcoin wallet receiving address, but MyEtherWallet transaction convert it to another address format that starts with '0x' and I think it's hexadcimal.

How can I know for sure that this address is actually related to the address that I typed??
I am looking for external generator to verify myself that the receiving address that my boitcoin wallet displayed turned into the hexadecimal code they show
You are trying to transact with two different types of cryptocurrency.

You cannot send/receive Bitcoin from an Ethereum wallet and vice versa.
