Delta exchange done and dusted.
Previously there was superb opportunities to earn 5 to 15% risk free every month. Was trading only this everyday.
Now it's gone, so withdrawn all the money back to binance
The strategy was giving 15% risk free by spending just 5 mins a day.

Didnt reveal it earlier as the edge will be lost.
Crypto Options expire every day at 5.30pm. I used to enter trade at 2-3 mins before it & then option will expire worthless at 5:30.
As you know, NSE options tick size is 5 paise & even at 3.20pm on expiry day, you can sell

(3/5)
for 5 paisa. Similarly each crypto coin has different tick size and it was trading at that price 5 mins before expiry everyday.
For example, previously BTC min was $0.5, solana min was $0.01.
With 100x leverage and say with $1000, one can sell 500 volume of solana at

(4/5)
5.28pm and that will become 0 at 5.30pm.
It was giving $0.01×500 = $5 per day, 5x30=$150 per month for every $1000 = 15% per month risk free.
The options here was 10% away from spot, so it's impossible for crypto to move 10% in last 2-3 mins. And there was enough liquidity

(5/5)
as well for that minimum value. Now the tick size is reduced to 0.001 in solana, so still one can get 1.3% risk free after fees. In other coins it crashed to 0.5% or less.
With 10% fees, now there is no point in trading other strategies after this opportunity is gone.
