Why wouldn't Polo touch this coin? I wasn't very interested in Waves during ICO but see it as a good opportunity now - a very well funded project which has been selling below book value. Also, they are smart enough to diversify out of BTC while the price is high. People have complained about Sasha placing a buy wall, but companies buy back their own stock all the time. The only real concerns I have are the ability for Waves and Lisk to hire blockchain experienced developers in what seems to be a tight market with a shortage of such skills. The other concern is that Waves has twice announced partnerships which didn't really exist, but there could be a language barrier with miscommunication as a result.
Polo doesn't have 'morals' around adding coins. These dudes are messing around.
The whole bots / manipulation story is another silly theory that sounds cool. There are pricing bots for BTC, and the price seems to be doing just fine.
