As many people have pointed out before me, you shouldn't trust any Bitcoin wallet/deposit system, which promises you interest - that scheme is most offen used by ponzi scams, which are likely to grab your money and disappear with no trace. If you understand the risks and are prepared to lose your entire investment - then by all means, you can go ahead and try to profit in the short run.

There are some investment funds out there, which seem to be legit (like Grayscale or Bitcoin Capital), but they aren't wallets - feel free to check them out.
