I'm new in the cryptoworld and new on Steemit. This is my first post

Hi, my name is dissi and as you can read i'm new here.

I don't want to tell much about me, except that i'm overwhelmed quickly with people. Especially when there are many of them, like on social media. So sorry, when i'm kind of strange sometimes. And i want to say that English isn't my first language. It's German, so i'm looking more for German users. But as long as you speak English, you're welcome ;)

My goal in the cryptoworld is, to make as much money as possible, but with the less "real" money input possible. So first i earn my coins with faucets like CoinPot and the moon-sites, or FaucetHub. It's now a month and i've made ~1,50€. It's not much, but i've made a lot of practical experience for the begin.
Now i'm in a group-project, which will start in a few weeks, where offers are posted. So i will earn more coins than with faucets. These coins i will invest in a site, called CoinLend. It's a bot, where you can lend your coins to someone for a few days and you became them back with interest - all automatic by the bot. The site seems legit to me.
In a later moment i've thought to start trading or to invest in ICOs perhaps. But i will see.
And i want to learn more about the cryptoworld.

So, i have some questions:

1. Can You give me tips about what else i can do?
2. Are there other (legit) possibilities to invest Coins with profit?
3. Can You recommend me some sites or better YouTube (or D-Tube perhabs) channels? (Prefers German)
4. Whats the difference on Steemit between the rewards 50% SBD / 50% SP and Power up 100% ?

Thanks in advance ;)
