Not entirely for crypto. before buying crypto you better know what crypto is and how crypto works so that it can make a profit. Many fail because they don't care about the coins they use as investment or trading. I have tried the exchange called CoinSwitch
Trade 300+ coins without creating an account and NO KYC is required on their exchange.You may please create an order for small amount.  if you face any issues in order creation or completion their team is available for 24*7 to support.Once you are satisfied with their service, you may then create orders of larger amounts. Their team is very friendly and helpful. Through their exchange  users can access the crypto-markets.
