Yes I have heard others do similar things. A few times I have used LTC which is still quite slow, ETH is nice and fast, I've also tried SBD which is the absolute fastest but it depends on how much liquidity there is on the exchange for the coin as you may end up making a small loss if you don't want to wait and there is a volatility difference.
