Many people think that bitcoin should move up in a straight line but this is not how the market works. Markets may show us many up and down before moving up and sadly people are not ready for these movements and sell their bitcoin before it reaches the all time high.
When someone hears that you are earning from bitcoin, they will mostly say that you are earning big and it is very easy to earn from it, but they are wrong. You will go through many stages, trials, and losses to get that profit you are earning now. It is like success in our life; we think the road ahead is just a straight line, but we are wrong; bumpy roads, curvy roads, and dead ends stand for trials. It is also the same in trading. People will say buy low and sell high, but not that easy since you need to know if this is already low or when you can sell.
