I am new to this field and still on learning curve. Yes there are lot to consider and also need to read a lot to understand the market. But sometimes things can go wrong too. It is a highly volatile market. But if we do some digging and do the home work we can find out the real ROI opportunities.
You have done a great work and thank you for sharing it with the comunity.
Happy new year to you and to your family
Cheers!
