Well Marco it depends on the mining setup. I am currently using only cpu for my mining. Bitcoin has a high share mining difficulty due to the number of miners mining it. Whereas Monero had a recent fork that had made bitmain Monero miners obsolete. Lowering the mining share difficulty significantly making it more profitable for lower tier miners. Regarding ICOs their has been alot of scams regarding ICOs so I am staying away from them as much as possible. And I will give your posts a look at :)
