Is it possible to invest 100$ in altcoin and turn to 7,000$? Have this ever happened to anyone on here? Is this even possible?.
Why would you say that? Of course, it is possible. This is how thousands of people get rich on crypto.
How to make it happen is another question.
There are just two options and no more: either you must have done something very very nice in your previous life (pure luck and you know nothing about investing and trading) or you are super smart and hardworking cause you spent much time and efforts to master trading to be able to find a gem you can get rich on (to recognize such a project is not easy to say the least).
