Good for you OP you found this strategy that works for you.
I am amazed of these things because it's really new for me, it's something new way for token offerings, which can drive up demand for the exchange token as users buy into participate.
This kind of strategy does require careful timing also research because not all crypto involved here are good, especially the tokenomics, you must consider it also.
It's really essential to be aware of the risks, as not all launch events lead to profitable outcomes, and the price of tokens can be quite volatile.
