Dual investment strategy for a newbie - APY more than 100% and time frame under a week?

I am newbie, who has been researching Crypto for the last 1 month :)

Here is my question,

If I am an Extreme HODLer, can I just keep on taking Dual Investments at the highest APYs (say weekly)?
If I am not going to sell any of my crypto, then is this NOT a good way to make a fair amount of money?
BTW I love Morte Couille's post in another chat

"If it’s not exercised I win ???? (I’ve accumulated more)
If it’s exercised I win too ????but with a loss that is the difference between the actual price and the price I did bet on. (If I bet ETH at 2000$ and it’s a 3000$ when the product expires I obviously didn’t make as much money as if I had just held my ETH)."

Is there any harm in this, say over an year, if I am getting 100 % PLUS APYs on all my transactions, and am NOT GOING TO SELL any of my crypto anyways? Would I have likely made more by not doing anything.
I am talking about short term Dual investment instruments of no longer than a week with APYs of over 100 %

Thanks in advance,
