Can someone tell me how is FEMA applied if i buy 100$ worth of bitcoin on international exchange? I want to buy bitcoin and then transfer it to my offline wallet and store there. I dont want to sell it for next 1 year.

Guys let's say I am Indian nationalist and have Indian credit card. Let's say I want to buy 1 Bitcoin which is 5000$. How much will buying from zebpay cost vs buying from CEX, all costs inclusive. (Currency conversion, interchange fees, exchange fees, etc etc).

Just trying to figure out which one is cheaper and by how much.
Thanks
