Binance is available in almost all the countries  and I vouch for binance from my personal experience and if coinbase is available then you can go for coinbase as it's a reputed and one of the primary key players. I have used these exchanges and both are trustworthy and reliable exchanges. Don't go for exchange with low volume as it will have huge transaction fees and you might end up losing if any error occurs while transaction as they don't have proper support like binance or coinbase.
