we may take other's review or comments about an ICO as an reference when you encounter a new ICO project or you are even a newbie to the market, before you started any participation you should be having enough observation, for example like knowing why the recent ICO would have gone might due to stricter regulations as every countries are emphasising or giving out outline or regulations in ICO projects or crypto-market at the moment.

I believe this is a common question on cen db and dec db, as i know in decentralized database, it can be differentiate into permissionless(bitcoin) and permissioned. How can i distinguish the difference on functions between centralized db and permissioned blockchain? what is the benefits of permissioned blockchain?

I think it is a good start to ask here, since information on google are really too much, but i think similar concepts or knowledge are more or less the same on most of the webpage. It would be good to view other previous discussion or comments on similar topics in this forum. You will encounter more problems and question definitely afterwards, i think you should not be hesitate to ask more here while you may summarise and tell us your understanding or research on the certain topics or questions you want to make sure your understanding is correct.

my route is
1. whitepaper
2. roadmap
3. team qualification and effort

做一個ICO所需要的事前資金也真的是不少啊

这个发merit的制度是挺不好的，你永远都不知道自己给的答案，就算有多好都是别人看看就算，没有人真的会给你一定的奖赏。感觉别的论坛也不至于这样吧！？

Just be very careful and think before you really pay for the ICO. Although many people do suggest that support and invest those projects that are already listed on exchanges would be safe, but i think the act to support new icos are also important, without enough capital support, it had sometimes let the ICO projects lead to failure.

Trading is an experience, even if you trade those token on exchange, you may still face lose of money. Therefore, I think you should experience it, the more experience you gain can definitely bring you to have another insights.

May I ask for more if the consensus types affects and got different flows on the chart?

Doesn't this seem risky? Right now Cryptocurrencies is not a really well-developed and a protective one, you can make trading for interest, while do not think that putting savings as cryptocurrencies would definitely give you very much wealth in the future.

I believe Binance and coinbase and some other famous exchanges are stable and trustworthy. A right exchange for you might be you think 1) the more verification / detail of KYC required; or 2) the more coins choice for you ; or 3) the most user-friendly display for you ; 4) low transaction fee . Be note that, not every exchange do have the same token, not every ICO can be successfully listed on every exchange, so if you are going to vote for any particular coin, check if the coin is being listed on which exchange platform first.

I use Ledger Nano S

Lack of the accountability from the local Governments/global authority.

Yes definitely, you may have a look of a passage introducing 11 startups to improve our environment

Buy the token when they are having public sale / private sale if you can be whitelisted. Note that not every ICO can be listed on every exchange site, there are so many exchanges sites and have different altcoin listed, so the "best" exchange site is depending on which exchanges are listing the ICO token you want.

Thank you for the advice, it is really really really useful, I feel touched when I also read the link that trying to help newbies to improve their posting. Thanks!

Hello guys, I am going to have a project to apply blockchain technology to the any industry we think we can bring the most benefit. Right now our group is considering applying on the supply chain field. Meanwhile, i believe I do not have sufficient knowledge about blockchain. I would like to seek help for the development direction.
For example, I think I should study on the type of consensus for the blockchain of the project, how about token? I think it should be not necessary to apply cryptocurrencies into the project? But should i also study the different types of ERC token type?

I am very frustrated and I just had a investigation on blockchain within a month time, feeling the online data are kinda messy too.

I think other than you should understand about the technology or benefits the projects can bring out, you should also look at if there are similar projects established before, no matter they success or not. You should also study on how the other projects can work successfully, whether on their ideas or their management skills which can lead their project run good, before you verify whether a new project is worth to invest on or not.
