based on my personal considerations, buying and selling is very difficult which is difficult for every 1, if you are a beginner, you will want a lot of understanding about this specific function as well as an additional sensible market if you are an industry without having the type to consider as well as understanding someone facing a big reduction. and no! I think nothing is impossible and difficult, we make ourselves difficult because of whatever work or task we can do easily through learning. So learning is a process through which we can achieve success and can make things easy and to solve problems.
