What is so perfect with this token? You are asking someone to do almost all the job of a developer. And paying with your worthless token? If I am the developer, I will just create my own token and not grab this opportunity. You clearly don't know how to develop a particular token.

I ln assumption that your project is serious, I would suggest you to hire a CM that's fluent in English. You tried to sell a product that will ease worldwide trip (I would like to discuss these "features" later on), yet your project seems to inadequately convey your message with one of the major language used by travelers.
A typical coin like this, it is very hard to get known by the people, sorry to admit but just don't get fail even if there is no investors.
We are trying to achieve our goal people's easily can buy through bitoxi exchange .. if any one who need to directly Exchange I am given him or her that opportunity to Exchange
Please check my previous post

10k USD? Well, to get all that previous forumer said will cost more. Nevertheless, nobody by this coin. Dev can try to find an angel, but he need to prepare high quality presentaion before.
to reach your goal 10k USD you need a good plan about how will the token works
you need a team, website, and advisor so there will be many people to see this project
so if you think that made a smart contract is the only option that you need to raise funds is a big mistake

I did not understand. What are all the technical details for? Personally, this code scares me, because I do not understand anything in programming. I think that many people can join my opinion.

About MEC
MEC is newly Released ERC20 Token / Coin this coin based in ETH
MV Express Coin (MEC) is a Safe and secure untraceable crypto currency you can locate easily where the transaction are how many holder have Market cap can check when ever needs ..
This coin Developed for World wide Travelers , they can enjoy this coin , if they have this coin they can exchange it to Fiat money through their MEC wallet our Target is to Reach 1MEC. More then $1000US dollar ' now the full world accepted many travelers are in this world every day every hour people's are traveling one country to another country , now a day's no need paper cash , if they have this coin they can change Fiat money or they can pay through their wallet .. we will contact world wide Visa and marster cards orriginal supplier , for the future events .. our plane is to make great this coin as soon as possible
