My approach is to invest for the long term, diversify a year's worth of living expenses into assets inversely correlated to tech, hold a diversified portfolio across different tech-oriented future scenarios and attempt to take a systematic, unemotional approach in domains that I understand and where I have expert knowledge. Tech and NVIDIA in particular have seen very significant draw-downs in the past and yet have been (in my experience) good investments since I started in 2008. Specifically, NVIDIA has seen extended draw-downs in the 60% to 90% range multiple times in the past. You just have to be (financially and emotionally) prepared for the ride and don't imagine you can time them. Anecdotally, Berkshire plays the safe haven / inversely correlated role for me though I've not proved it. There are always segments in tech doing well so I research beyond the Mag 7 and infrastructure. See bio for my research. [My opinion and not investment advice].
