I wanted to know if anyone has an answer for me. If i still have my public/private key, can i withdraw the BTC that i previously put into PlusToken using those methods since Plustoken has shut down?
its already answered above its scam project there is no way you can have back your money stolen by them . Just forget about it and move on that the only thing you can do by this time. Find other investment that will not turn scam someday legitimate real world business what you should looking now not any investment scheme that offer some amount of money in exchange for your investment.
It baffles me how people in 2020 still invest in Ponzi schemes and yes PlusToken was a smart scam as they pretended like they are using the money from people in developing wallet and other services but one has to imagine the abnormal returns they were providing was beyond imagination and if they had such a sustainable and scalable project they would have taken loans from banks.
The worst part when I was reading about their scam was they left a message in transactions which read as "sorry we have run" this just makes me so angry I mean like scamming was not enough for them so they decided to rub wounds with salt. I mean how inhuman one can get now a days, it is beyond imaginations.
