Describe the problem:
So Ive once send a friend like 300 dollar so he can purchase safemoon in 2021. I have like 1900$ (1600$ profit) of it. He send that profit to my binance acc as bnb. The question is, how to mark it as a spot profit.
Which exchange/wallet is this regarding?
Binance
How did you import data into this wallet?
What have you tried to fix this so far?
@erkler232 You cant tag a Deposit in Koinly as profit.
You need to ask an accountant local to you about how to represent this 
But it sounds like your friend took the tax hit here
Profit and Gain occurs when you SELL or DISPOSE of an asset typically.
When you sent $300 to buy you safemoon, this is not a txable event since you did not trade any crypto.
Your friend, when he sent you 1900 worth of SAFEMOON, will have the tax liability, since they disposed of the asset.
