It's a very delicate venture investing in cryptocurrency. It's something one should be careful about and make a dedicated effort to research well before going into it. Most people just hear of successes made by others in crypto and because of that, they feel its an easy stuff and just dive into it.
One thing I can say is that cryptocurrency is a business for the strong in heart and determined. Also, patience, much of it is required when treading the part of cryptocurrency. Its best to start small, at least with established projects, Bitcoin and Ethereum before moving to upcoming projects like Veil, Harmony, etc.
Like I earlier said, research is of uttermost importance when choosing to invest in cryptocurrency.
The point is not anyone can invest in bitcoin and then profit easily. bitcoin and crypto have a big risk you know. need people who want to try hard to want to learn to understand the market to be profitable, need people who are patient waiting for prices fall to rise, need brave people from fluctuations that occur.
