The current situation on the market is highly ambiguous. You can hear different opinions. And everyone believes in different things. But none of them with confidence can not say anything.
You must have your own opinion about the market and your own assumptions. Only this will give you strength and confidence in your actions.
When I first wanted to invest in crypto currency, I was also covered by fear. And only after I explained to myself why I do it and what exactly I am willing to do for earnings, I without any fear invested.
I already had a strong belief in crypto currency. I was confident then and now that the prices of currencies (for some) will grow. Since then, there have been many things. I got a huge amount of experience and to this day I have never regretted that I invested in crypto currency.

P.S. I invested that amount that I was not afraid to lose. Later, when my investments paid off and multiplied, I took away the money that I invested in the beginning.
