Hello, i'm kinda new on Crypto.
I've  seen that there are some altcoins that can be send via the same Ethereum address.
Can someone explain me how can i see my altcoins on my ethereum wallet?
I tried adding my coionbase ethereum address on https://etherscan.io/ but i don't see nothing.
I have 0.01 ETH on my coinbase adress that i got few weeks ago from another coinbase eth wallet transaction?

Can anyone explain me how can other alctoins can be send to my eth wallet? And where do i check what altcoins i have on my eth adress?

Thanks.
