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.
OP, the title is misleading. It should be Why I prefer mining than investing in ICO/IEO. Anyway, you're actually right but you also needs to consider the risk in mining. What if there could be some problems in your rigs, worst it got broken. And also you need to consider the electricity your setup is consuming.
