I have started to trade with small amount, then made some mistakes, lost money
I realized that i have to learn trading, read books, watch youtube, etc.
Then I started to trade on paper, just to search good points on graphs, and mark them
Now I got a lot of new knowledge with this practice and started to trade with amount about 5-10% of my entire deposit

I still remember the first day I invested in bitcoin. I spent $ 150 in exchange for 0.06 BTC. And for one-month trading, i only 0.012 BTC left. After learning about the crypto market on some blogs, I understood a lot of things. I now earn 0.625 BTC with only 0.012 BTC initially
