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.
