Thank you bakd247 - I thought (and could be wrong) that any ERC20 coin could be transferred from Coinbase to myetherwallet or that adding the LTC address and decimal # on my etherwallet under the "add custom coin" would take care of it.
If LTC is not an ERC20 then I guess that would be why I am getting an error message from Coinbase about transferring to myetherwallet address. But they don't bother saying why.
Trying to get info from Coinbase is nearly impossible. They are either understaffed altogether or understaffed on the customer service side. That's why I hope to find a much better company to go through.
Thanks again for your reply.
