Although a clone of P3D, Proof of Weak Math has far better dividends without going over the top (e.g. Po50). It also has the strongest community of all the clone "pyramids". The whitepaper is genius, hilarious. The contract is safe (no secret exit door for devs). The community is full of hilarious PoWH investors that decided to diversify and ended up benefiting greatly (including myself). And it's essentially brand new. A lot of leg room to grow : If interested: https://powm.io/?masternode=0xb9cc1875eec851548cb7eca33ecc643fce9d44e3
By the way I turned 6.3ETH into 8.2ETH today...can't say the same for PoWH3D
