I don't think a token is a solution... and if you really want to think AVa is the solution then you are wrong because AVA runs under ETH blockchain. So, if you see it that way then you mean ETH is the solution and not one of its multiple tokens.

If you want faster confirm coins, then you should look at dogecoin, which's a real coin and it has blocks each minute. And the transactions are really cheap too (1doge).
