Of all shapes and sizes, I come in many. You drop coins inside me. What am I?

I take from everyone, rich or poor, but I am not a thief. What am I?

I'm a promise of protection, a shield from uncertainty but I'm not made of steel. What am I?

A currency of the future, you cant hold me but I hold great value. What am I?

I'm a pool of money, managed by experts. People share in the gains and losses. What am I?
