4x Crown crafts as an investment

Hi Guys, since I'm old and have some money left, my plan is to reinvest in my inventory in the next few weeks. I used to have a crown foil themed load out since I really liked the sticker in go. Even though it's not as good as in go, as I was looking for skins and I feel like I really want some 3/4x crown crafts as my play skins.

My Problem is that it seems that people still want some hefty overprice for these crafts, but the sticker itself is "only" around 330$ right now.

For example two of my dream skins are St me Vulcan with 4x crown. I found one on float for 1,4k€ (std st mw Vulcan is around 670€) and an st awp graphite fn for 880€ (base skin =290-300€). So even though I could afford it, i feel like I'll never get that money back, if the sticker doesn't drastically increase in price. What do you think would be a good sticker % overpay for a 4x craft? The thing is that I don't see any cheaper options on higher grades

d skins. Would you stay away or take a gamble with the markes as it is?
