It depends on the purpose of kyc and if the said project is worth it. I have nothing against kyc personally but most of my friends don't want anything to do with projects requesting for personal details. Most times kyc get introduced cause of abuse and multiple account spamming which is quite understandable. It is always right to introduce kyc at the beginning of any project agreement or campaign not towards the end or at the end.

When you think about it, if your bank account is tampered with by a fraudster there is always a way out to track your funds and recover it. There are ways the bank can track the transaction and the details of the fraudster will be revealed and there is a high probability of recovery your funds but I can't say same about losing your funds to fraudsters in your crypto wallet. Blockchain is fully decentralized it almost impossible to recover funds lost to fraudsters.

A lot of coins will eventually fade out while the ones with solid foundation will exist for long term. Some team members can't manage a project probably cause they were too greedy or they misused funds raised for the development. Most of this bad projects get delisted on several exchanges and eventually stop existing. This is a major disadvantage of long term holding in my opinion.

It is really risky investing in new coins without checking out for a lot of factors. Before making investment on  any new project, research on how genuine the team behind it is and if they are  very professional when it comes running a project. Check the social media handle and some of their partnerships before investing. I personally don’t invest in new project, but the ones  existing already cause I will  look after their past performance and how strong their investors their community. The reviews from the investors is very important. Always do your research very well cause a lot of new projects can exit scam easily.

It depends on the particular bounty campaign and the project team. Some bounty projects will demand for kyc after the end of campaign which is very wrong and unjust cause some participants aren't comfortable giving out their personal information and wouldn't have wasted their precious time joining such campaign. Asking for kyc after campaign is wrong, it should be stated at the beginning of a campaign, many hunters end up losing their rewards as a result of this.

I don't think it's stupid cause everyone has the right to sell their assets at their desired time. But I think it is a bad idea selling for loss or panic selling when we can always hold to make profits. Selling at the top and buying low is the best strategy I know. Top 10 cryptocurrency will always remain relevant and I think no one should sell them for loss, I believe mass adoption is near and those crypto will eventually become a gem cause the demand will be very high.

Long term holding cryptocurerncies has its advantages cause investors won't be bothered about the volatility issues in the market. Most times people panic sell when there are certain volatilities in the market which result in big losses. Long term holding has its disadvantages cause some of the crypto being held might lose its market value permanently which will make it a shit coin eventually. Sometimes the traders lose their private keys of wallet recovery phrases for most of the long term holding.
