Good choices. Miners will be hard to gather large amounts but little and often yields big results I guess.

As far as deciding which investments to go into, I basically do it on feedback from posts like this. I'll engage with token holders and get a feel for what people like and dont like. Big investments of say 5-10% plus of the total fund value would be decided on by token holder vote. I try to be transparent and I dont over complicate things so everyone understands what we're involved in.

Good question :)
