@chinmay-ashok having gone through your answer/post and response by @RobertB4444 ,
1. I agree that the cost basis of the crypto holdings is the amount you paid to acquire these in US$ of the day i.e. if you bought at different times then you need to use dollar of the day for each transaction -- use any published rates
2. Depending on your longer term goals for yourself and the holdings ( Crypto) : if you sell and re-buy these then any gains may be outside US tax purview ( assuming you affect the transaction before you pass the Substantial Presence Test and therefore have to contend only with India Income Tax ); if you do not sell and hold these as you are today, for US tax purposes ( once you become a Resident for Tax purposes ), it is immaterial whether the Crypto was bought in US currency or another or when -- US will still tax you on any gain on DISPOSITION. Thus there is no urgent need/ advantage by selling/transferring the Crypto to US exchange.
Does this make sense ? Is there more I can do for you ?
