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.
Whenever people talk about investment then i always say bitcoin is forever best for investment. But investment has a rules, invest your capital when coin has down price and sell it when coin price is up. In this wise, we gain profit. without profit every business is useless. So we do invest to see the principle of investment and search about it then definitely we could get profit in all over altcoin.
