Comic Pingu

I'm 20yrs old and have been reading and collecting modern series since I was a kid. After listening to my friends endlessly talk stock and crypto currencies, I've decided I'd enter a side profit/flipping realm that I'd really enjoy and have an affinity for. So, I've recently begun collecting some relatively smaller keys (Avengers 8 & 57). I see a lot of big keys are blowing up right now and their FMV's are incredibly exceeding last year alone. So, my main question is, do I buy into an inflated MCU Spec market, or wait for a dip (that may never occur). I have comic knowledge but not so much market history knowledge or the volatility of it. Disclaimer: No I do not expect to pay my way through life on the backs of books... Just for the fun of collecting the books then eventually selling for some profit. Thanks

I am at a similar crossroads with the Tynion signing. I have two "Something is Killing The Children" one per store and lcsd variants that will only have significant value if graded 9.8. with the $90 sig&pressing for each book, I heavily debate this gamble.

That is my exact concern. $300 for a signature, that may only be valued by a select fan group. Coming out to over $800 total cost, the odds of me making a sizeable profit seem very slim...

Would anyone recommend getting Avengers 57 signed by Paul? I recently got a 5.5 for $500, and can't decide whether the $285 sig is going to be worth it. Moreover, is his signature even desirable for that key? I can't find any selling history of his signature on ebay beyond posters
