so EDR Coin it is , I hope you have invested less in it .. all such cryptocurrency which gives bonuses and all are just to attract investors but that also mean that they do not have good backing structure (investments)
They did plan stopping maintenance eventually but as you said they are doing it early. The reason is simple that they are ripping people off.
I would suggest you pull out your money from EDR Coin and invest in some reliable Crypto (eth or ripple or such) and the current time is a good one to invest as most crypto is dipping down in graphs
EDR Coin can turn out to be a ponzi scheme.
