Reasons why i prefer mining coins than investing a dime on IEO/ICO projects
1. My profits is assured.
I dont have to wait for a project to do x3 or whatsoever to get profits on my invested cash,with better mining rigs and good calculator you will know when your ROI will come.
2. No worries of getting scammed
I dont have to investigate an exchange before investing or wasting time doing research on projects before investing,all i do is mine ETH and sell for fiat or decides to hold for a little while.
You ask about your personal opinion "Mining and investing in IEO/ICO ". Until now I tried to invest and do a Bounty campaign. It is, in my opinion, easier and can give me a profit. Especially in the year 2017, many of the advantages I get.
I have not been mined because I think it is very difficult and requires supportive equipment. Although investments can deal with fraud, I think it's not a problem, because before determining the choice we can do some research.
