TOKIA - ICO Token - INVESTOR ALERT JAN 21 2018
While everyone is hunting for the best ICOs in the cryptocurrency market in 2018 with their hard earned money, we have come across one that is a little obscure with very little information of importance and value to investors. This is the TOKIA (TOK) token which is running Round 1 crowd sale. They claim to be a mobile wallet company seeking crowd funding.
As other content creators on Youtube such as New Kid On The Blockchain,who published his video on Dec 30, 2017 and Bitraged, who published opinion on Jan 4, 2018 on TOKIA token, we are also of the conclusion that TOKIA token sale is missing a lot of pertinent investor information. One such example is on their webpage, in FAQ as below:
**************************** source: https://www.tokia.io/faq/#33 *******************************
Why can’t I find TKA on exchanges?
This is because TKA token is not listed on exchanges yet.
The TKA token is expected to be listed on exchanges on May 1st, 2018.
Will I get a confirmation email?
Yes, after you buy TKA tokens you will receive a confirmation email.
Where is the smart contract?
Smart contract will be uploaded to Github on 10th of December.
Audits of the smart contract shall be completed by 19th of December.
When do I get my tokens?
Tokens will be delivered with smart contract on 20th of December.
Will I be able to get a refund?
As stated in our whitepaper, all transactions are final and refunds are not possible.
************************** End ********************************************
What is disturbing is when you check on the facts, specifically as they stated such as, "Smart contract will be uploaded to Github on 10th of December." upon going to Github, they have indeed put a page at, https://github.com/tokiateam/SmartContract/blob/master/contracts/TokiaToken.sol with the following code:

After going through the code, that they put on Github in late December 2017, there is no actual contract to claim in the Ethereum ERC-20 platform. So if you sent ERC20 token to their smart contract at, 0xdaE1Baf249964bc4b6aC98c3122f0e3E785fd279
most likely it will be a very long time to see anything funded in your Ethereum wallet. TOKIA team tells you how to send them your funds, but they fail to tell you how to claim their token which seems very strange. This is not a normal experience with most ICOs, You will recieve and email that you have funded them and we have not seen any emails about confirmation. We emailed the TOKIA team and have not received any formal explanation of verification of when the ERC20 smart contract will become active on the ERC20 platform which is pertinent information for token funders. Putting some computer code on Github does the public little help. It does help the developers but that's about it.
Also when we researched a professor that they mentioned on their website as advisor, Professor Wulf Kaal, his information is available on youtube and on University of St. Thomas School of Law, Minnesota but that does not answer pertinent investor information and nowhere an you find him on social media talking about TOKIA token which seems strange. Not only that none of the founders are on Youtube, Reddit to interact with the general investing public. Hopefully TOKIA team will come out and clarify things for the public. That would be much appreciated.
If anyone else had or has a different experience about this company and its projects, would be greatly appreciated!
