BitShares is better technically and on the aspect of having a true decentralized and stable token. However that is not everything. Waves is way better funded, has more momentum and way better PR than BitShares. Their DEX even if it isn't as good, looks better. So people will naturally go there becasue user experience matters.
Either way, I think what matters the most and what ends up making the difference in the end will be liquidity. People trade where's volume. So better pump these bots, which are one of the best things happening to Bts imo. Anyone can provide liquidity even if only a tiny bit.
Btw, the way that was handled on Twitter was bad. It doesn't look good or show confidence on BitShares' product. Just focus on BitShares and bringing in liquidity, let others alone. The tech is here, so it's just a matter of time until the cliente looks better and liquidity increases.
I think BitShares should take advantage of this altcoin bubble to hire someone or a team of UX experts to do a rework. It will end eventually and might be harder to do so in the future.
