Actually many things :
- Am I sure to really understand what crypto money is?
- what are the risks of crypto-investment ?
- How much FIAT money can I afford to invest on a monthly basis ?
- What could be the possible outcomes of a state regulation of the crypto world
- Why do I want to get involved in crypto world ?
So you really have to invest fiat money every month? No chance to earn something and then continue with the profit you've made, instead of investing more cash?
