OP I've never seen anyone gain as much as you say. Cryptocurrency is a system where you cannot say for sure how much profit you can make by trading or investing every day. But you can keep your $4000 in bitcoin investment so you can profit over time. I see you're new here so I'm not trading you. Because you can lose your dollars anytime on the trading platform. But if you invest in Bitcoin then there is no chance of losing your investment. Even after investing in Bitcoins, if losses occur, you can still look forward to recovery. So I want to tell you that it is not possible to earn 100 dollars per day but you can invest in Bitcoin and it can give you good profit in a certain period of time.
