I don't know how it works in your counry, in my you can buy ETH with fiat without verification at an echcange office like bitcantor (they allow instatnt bank trasfer which takes minutes to send) and then send ETH to Poloniex (verification takes minutes there)The whole procces takes you about 30 minutes. If you use bitcoin, you can get stuck in a que for days, waiting it gets to an exchange where alts are traded.

Not to mention that's its bucket loads cheaper to do it all through ETH
