As we know today BTC just dropped below $40k. I am having a very strong feeling that this would be the perfect time to invest,
You don't need to use your feeling. Everyone must understand that it is the right time to invest their money before the Bitcoin halving. If we look the history, Bitcoin should begin to increase massively after the Bitcoin halving.
I agree with you here, but does not the profit get less during halving when more and more individuals know about this chance? So the profit should be less this time then 4 years ago and so on.. or does it work in some other way?
