I consider Swyftx to be similar to Digital Surge. Both Swyftx and Digital Surge are not ideal if you're trading Bitcoin and Ethereum, but if you're looking to trade smaller cryptocurrencies, they're definitely the best 2 exchanges in Australia for this purpose. So definitely sign up to Swyftx if you're looking to trade altcoins. It's hard to say definitively whether Swyftx is better or worse than Digital Surge. I recommend signing up to both, and when you're trading some altcoin, check the prices on both of them.
