I think it is stupid. Why would someone want to own Bitcoin indirectly via a third party, if they have the option to own it directly? This
introduce a trust relationship into Bitcoin, that we do not need. When you own Bitcoin, you should not have to rely on a piece of paper,
issued by some centralized service or entity... You buy it, and you own it 100% or you do not own it at all... if you have to rely on
someone else. Exchanges, where you do not have the Private key for your bitcoins... is the same thing.
