1) HOLD - Buy currency like BTC/ETH/SOL/BNB and hold for long term
This is the best way that I do also for crypto investment, especially for long term period. It's just that, at that time, I missed SOL, for other coins, I am very grateful to have them since the price was still small. And it teaches me very well to prepare for the next bearish period.
Hacking have bad reputation but if they want try looking bug at some project I believe have opportunity earn much money than how stolen from hacking, I think many new or old project always protect their side and make give away for their bug, if you find bug at any project get possibility with higher payment.
Unfortunately, hackers never stop doing it and continue to look for potential victims, both on a small and large scale. Caution and vigilance are very much needed. And for developers and also owners of certain platforms, it is indeed mandatory to tighten and strengthen their system security because hacking, phishing, and scamming may be targeting.
