This bill is so bad it's hard to understate how bad it is. Imagine you top blast $10k into a token and get 1M of the supply, then it nukes -99.99% in an hour. You sell and take the loss. Then 29 days later you buy back in with $100 and get the same 1M of the supply. This new bill makes it so that -$10k loss doesn't reduce your taxes, making you owe more on any other gains you might have.
And if you're long spot and open a short, you might owe money on it as if you sold the spot position.
If this passes we are going to goblin town
