M Gdqcoin Reviews 

Avoid this company if you don't want to lose any money. They don't like to pay , always asking for tax fee and when you don't pay, they don't grant your withdraw and close your account. Avoid them, BAD INVESTMENT. display picture assisted in withdraws.

I was part of the group for a while, but I did not invest and just monitored them. The whole group consisted of bots and fake professor, do not invest, this a scam site.

Be aware, all is planned to get your money.
As already written in other comments the whole story is true. Actually I made the test with a small amount of money. 1. Test withdrawal was positive, but actually after many successful tradings with more than 100% win at each trade the balance of more than 50k is not possible to withdraw. They ask a security fee of 5% to proof to be a legal citizen.
If you don't pay, they claim your account and close it. Pure robbery. Fincen.gov and BaFin told me not to pay anything, because governments don't ask for fees.
The terms and conditions of gdqcoin are unknown.
So be aware of this Fee- Crypto-SCAM!

Easy to deposit but you're not getting your money out. I learnt the hard way but glad it all wrked out. Reachme 4 urs

its fake Prof. Krease Brown is not Seriosität and the coins are not real. The several User are fake Accounts. Do not pay in this gdqcoin!

This IS a SCAM.

The Professor (Williams D Blair) and his Assistant (Lsabella) will ask you to register with an exchange named GDQCoin.com - (Singapore) which claims to have a MSB registered in the US.

Besides a few main tokens listed on every exchange to make themselves look legitimate, this exchange also lists some proprietary (fake) tokens that do not have whitepapers AND these coins DO NOT EXIST on ANY OTHER EXCHANGE!

MYQ/USDT
NSHC/USDT
PHTX/USDT
QIV/USDT
SLET/USDT
SRHT/USDT
XYP/USDT
ZAQ/USDT
ZPH/USDT

They invite you to join a whale group as part of Tsunami program where they pump and dump these tokens 6 days a week. Minimum investment for the lowest group is 50K.

The groups and investment requirements are
Humpback Whale - 1M
Whale - 500K
Shark - 300K
Dolphin - 100K
Fish - 50K

Everything seems to be going great and your account appears to be making a lot of money however, surprise surprise, when you try to withdraw your funds, they freeze your withdrawal and hit you with a notification that

"GDQcoin responds to the request of the federal government. Your current withdrawal will be sent to the Treasury Department for verification again by the system, and FinCEN (Financial Crimes Enforcement Network) will intervene in supervision. Therefore, after preliminary review, withdrawals are suspended."

and...

"in order to prevent illegal activities such as money laundering, you need to pay a deposit of 0.6% of the total funds as a deposit to ensure that you are a legitimate user and have not participated in any illegal money laundering activities."

DO NOT PAY - No LEGITIMATE exchange will ask you to pay a fee to ensure that you have not participated in money laundering. This is a scam to get you to pay an additional ransom.

AML - Anti Money Laundering processes will only require that you complete additional documentation. Never pay more fees.

I hope this helps others.
