Many novice "investors" have already lost 20-30% in the past two weeks,

But let me tell you something: if you lose more than 20% in two weeks, you are not an investor at all,
You are just a complete gambler dreaming of getting rich overnight — that is entirely an illusion,
Real investors almost never lose this much in such a short time,
Because they know how to allocate capital properly, and how to hedge and diversify risks.
