So I bought crypto using the Coinbase app but the fees are a ripoff at 4% (That's 8% roundtrip!) I need a place to trade on mobile where I can get dollars in and out and the fees are more reasonable. Please suggest.
Can you share the name of your country you are coming from? If it's not India, Zebpay (a formerly Indian Bitcoin exchange) is your way to go and buy BTC cheaper than Coinbase and their KYC process is smooth and fast, will get you done with buying your coins in no more than 24-48 hours.
