Where to start

Hi guys
So Friday i will start my crypto journey. I'm so excited.
I will put 200 pound to yobit. I already registered in and looking around. I don't want to lose everything in the first day so i just give some time for myself to learn and i will put this money to investbox until i will be confident enough to start swing trade and day trading. I found one promising coin which pays 10% a day but the supply is unlimited...
It sounds to me every 7 day the coin supply 100%more. If i am well its mean th price should drop to half as well .....or???
