Waves is very interesting project with a strong and fast growing community.

Perhaps the team of 88coin is trustworthy and the project is techologially powerful I don't think it's able to be more than just 'another coin'. Possibilities of existing cryptocurrencies are used very little. The market hasn't a problem that 88coin solves. As I see from the whitepaper they just create a wallet and issue a plastic card. Such services are working already. So 88coin doesn't look like new milestone in cryptoeconomy.

Check out my own research https://bitcointalk.org/index.php?topic=2245059.0. In my very humble opinion, there are much more interesing projects in the list
