I think the best projects to earn a ton of money are still blockchain, defi and NFT. But it all depends on your investment profile, if I think it's suitable, it's not necessarily the same for you. So it all comes back to the risk profile of each investment.
Yes, in general blockchain, defi and NFT can still be relied on to make a lot of money, even though all three have different risks, but for everyone they can still choose the three if it is considered very suitable for them to live.
