this like all the other DAPPs on the ETH blockchain,
are pretty much glorified, reworked and reworded Ponzi schemes
to those not familiar with them, they are extremely volatile. if cryptocurrency in general has a volatility rating of 7 out of 10, PoWH3D and other DAPPs like them have a volatility rating of 11/10
They are often ran by the same group of individuals who often open up or start new DAPPs through discord and they get new members to join as a means of milking more money from their users.
PoWH3D and all these other DAPPs usually copy one another's coding and sometimes they don't even change the links for the websites which they point to.
I would enter this and any other "Proof of" DAPP with extreme caution.
the only people who are successful in these DAPPs are first and foremost, the Contract creators who premine the contract and then followed by Whales who have enough ETH they can buy up massive amounts of the coins.
New crypto users, be very cautious. do not enter into these DAPPs with false dreams of massive profits, you will get rekt
