I'm trying to find a way to duplicate my BTC before the halving without incurring in high risk...
If someone has any way to double their bitcoin without risk, I don't think they will be willing to share it with you, they will take advantage to do it for themselves. But I can assure you, there is no way to do it. There's no way you can double your money without any risk, you're getting too greedy, my friend. If you do not give up this intention, you will soon be caught in the spiral of greed, like to get rich quickly, and you will pay the price with your own bitcoins. Crypto is not a get-rich-quick market without risk.
