Whatever the background to the pump and dump coin you mention it was the alleged hacking that made a lot of victims come forward.
oh about the shitcoin story this damn scammer created:
a few years ago when i entered the crypto world i was making faucet and i realized that making faucet would take centuries for me to have many satoshis so i sold my computer stuff, i remember that day it was raining a lot, even raining i went to the bank and went deposit the money in the bank to buy bitcoin, after buying bitcoin i created an account there on poloniex and yobit, i didn't know at the time that yobit was a scam and so i bought some altcoins on yobit... god in heaven, i regret it to this day. this scammers was on yobit chat encouraging people to buy altcoin from him (I forgot the altcoin name, I think it's called TGV or TPG something like that... ) but after these scammer kept spamming yobit chat, shitcoin was removed and dropped from 400 satoshi to 1 satoshi, only after years I realized that it was this guy who had created shitcoin and was the same one who spammed yobit.
I am sorry to read about the manner in which you were scammed. I had never heard of TGV or TPG scam and maybe almost all of the scam tokens and coins made by Yobit but how can you be sure it was TillKoeln behind the Yobit chat trying to encourage people to buy it?
I agree in all probability there was no hack and the attractive Dogecoin price at the time twisted his mind with greed, that is almost a certainty but you are a newbie yet you seem to know a lot about unnamed.exchange and scammer TillKoeln. How?
Not a newb. I just don't post often.
I apologise in the event you felt offended. When I used the word "newbie" I was referring to your current rank in the forum and yes I noticed you post sparingly even though your account was created in 2016.
