I have never made any investment in mining projects through IEO. This is actually quite risky. It has a number of factors, such as a business that does not guarantee financial statements, so I cannot know how much profit a quarter makes. Besides, when implementing IEO, the team also does not guarantee the use of profits to increase the price of the token.
That's why I don't invest in such projects. because mining is very important in terms of profit, if I don't get a share of it, I will never invest.
