1. None of the coins I hold have increased in value. Is there still hope?

I am afraid that this question can only be asked by ourselves. We can think about it ourselves: Is it because the coin itself has a problem or the market has temporarily ignored it? If the coin has no problem and the market has temporarily ignored it, then it is not a big problem. Because in the bull market, basically every track will rotate once, as long as the coin has no problem, it will rotate sooner or later. If you don't know whether your coin has a problem, you can recall why you bought it in the first place?

Now let's see if the reason for buying it in the first place is still right?

If you can't answer these questions, it proves that you still don't understand it. Since you don't understand it, you are upset and feel hopeless. It's better to simply change it all to Bitcoin and Ethereum.

2. When you first enter the coin circle, you have not experienced a complete bull and bear market, and you have no concept of risk. I have always advocated that you must use spare money for investment, and never use money that affects your life, let alone raise capital by mortgaging assets. It is very risky to operate with such a high leverage. I think it was good luck that there was no problem with this operation, but everyone's good luck is limited. Once you have bad luck once, all your efforts will be wasted. In addition, even if the final result is good, the process of operating with such a high leverage is very destructive to people's psychology and physiology. In this process, you live in fear and anxiety every day. It is very likely that your psychology and physiology will have problems before you see the fruits of victory. And once your body has problems, no amount of money will help.

3. After reading Vitalik's article, he said that if faced with quantum attacks, Ethereum can adopt a rollback method. What do you think of this method? I understand that Vitalik is talking about measures in very extreme situations. However, if this situation really happens, it is not surprising that Vitalik did so. Because after the last DAO incident, Ethereum carried out such an operation. I think such things should be avoided as much as possible. Because once it happens, whether it is rolled back or not, it will hurt the consensus of at least half of the community. In addition, I think the probability of this situation is very low, and anti-quantum attacks have been deployed and arranged in the future development path of Ethereum.The Ethereum community also has a team dedicated to researching anti-quantum attacks. So overall, I am not too worried about Ethereum being attacked by quantum attacks.
