GPU is more of secure investment than asic.
i have both and these days when crypto is down, GPU still making reasonable while i have to shutdown asic due to very low profitability.
That's one of the reasons why you should choose GPU/ASIC. I have a mining rig and ASIC but i have some strategy when buying ASIC at moment crypto price is on top then I "push" ASIC to get 3x profit from ROI and from that profit is used to buy part by part mining rig.
For now, I doubt to buy
both
