Well, depends on the viewpoint you take : is it a gambling site or serious work with wallet and savings account. From the first, it would be negative, yes. The second is a very different matter. I am totally not interested in the gambling part.
Very good point, Ludwig. Perhaps a separate domain for the wallet and interest would be a good idea. The large gambling/faucet volume would be offloaded to a different server, so people who have large quantities invested can have a less congested access point.
