I can give you a hint to 8th point:
Don't bother with mining. Just buy the altcoin you like on the exchange and hold it

Best strategy

Thanks for the reply. I will manage my expectations then... but I think I want to do both... I also starting to invest in ICO's and I would love to understand more about blockchain and mining, so I would love to experiment with mining in practice to get a good understanding of it and maybe, thats something extra, make some profits...
Further practical tips for a starting miner?
