There are many chains out there.

Fantom, avalanche, bsc, aurora.

I can send to most of them.

Most of them have uniqe token.

FTM, AVAX, BNB,

but aurora main token is ETH.

And if I try to withdraw ETH, there is nothing in binance that allows me to use aurora network.

So how do I feel my aurora metamask with money from binance.

Which coins I should buy?
