1. Smart contracts you interact with could have backdoors, weaknesses, or be hacked. An audit is never a guarantee of a project's safety either. Do as much research as possible on the project and understand that investing always involves risk.

2. Regulation could affect your investments. Governments and regulators worldwide are taking an interest in the DeFi ecosystem. While regulation and laws can bring security and stability to crypto, some projects may have to change their services as new rules as created.

3. Impermanent loss. Even with IL insurance, it still is a large risk for anyone who wants to get involved with liquidity mining. The risk can never be totally minimized.

4. You may find accessing your funds difficult. If you are staking through a DeFi project's website UI, it might be a good idea to locate the smart contract on a blockchain explorer as well. Otherwise, you won't be able to withdraw if the website goes down. However, you will need some technical expertise to interact directly with the smart contract.

Only after I speculated on coins did I realize the importance of time. I feel that I have learned a lot here, and I have seen the investment experience shared by everyone, as well as some deeds of personal experience.

I think it makes a lot of sense, and I'd rather spend my time here than playing games. Besides, playing games is not necessarily fun here, what do you think?

What I get from investing in cryptocurrencies is not only happiness, but also a lot of investment experience, and what I get is the opportunities given by this era.

The joy I get in this game or a little bit, it doesn't matter if I make money or not. Because I think the investment I participated in is the fairest investment of our generation. Although there are a lot of black box operations and insider inside, I think the cryptocurrency market is fair compared to the stock market and the housing market.
