I know that for sure because I won a contest (Football scores) once and this address sent me the prize. 1000 LFEc tokens.
First, I thought that they were only doing a buyback, but when I followed all transactions I saw that they are selling and buying from this account. Totally manipulating market. I suspect they want to do hype/FOMO thing because they often say that the token will get 5usd before Christmas.
This token is listed on StellarX and interstellar.
Follow the link above and you will see the pattern.
PS: if you anyone wants to bring more evidence, be welcomed.
Ps: I followed this project for a long road as a BH.
