There are many exchanges in India for buying and selling crypto, Consider these 4 points before trusting an exchange

1. Is the team transparent
2. Do they have an active community and team who are handling these
3. Do the exchange have good liquidity to buy/sell crypto anytime
4. Do they provide support on time

If you feel they are ok with all the above points then go and choose the exchange

FYI: Please keep track of all your crypto purchases

Cheers
