Yeb you should be cautious about that Wallet Link that is provided from the OP.
First the Account is an old Account that was registered in March 08, 2016 and wasnt online here for over 8 years.
This user recently woke up from a long period of inactivity.
Possible the Account got hacked.

After 8 years the first he is writing is a new coin with an suspicious 100 MB Wallet download Link.
The explorer Webpage is also hosted from not secure Webpage.

Looks very suspicious all in here in my opinion , will be watching it.
