My strategy is to increase the number of Bitcoins I have. Just like you said, the Bitcoin price in the near future has the potential to reach at least 30-40K. That's why you say how much Bitcoin, so much profit.
I have been also planning to increase bitcoin and ethereum since the prices now are very cheap. But I am also planning to hold it since I dont think the red in the market will be over soon, so patient and wait for the future.
