I hope you are right...Good luck!
I think today many people will say: I would have bought. The course is really good.
and where the course is in a month you do not know yet. I should have invested too. but I was scared

Hindsight is always 20/20. Funds for most of us are limited and we invest where we believe it will grow. We make both right and wrong calls.
For example, many regret not making profits out of BTC which went x4 over the past 5 months? They fail to see that there are coins that is making that (and more) now in just a few days!
Opportunities are always here but finding them AND having available funds AND guts to invest...(all 3 must be align) doesn't always happen.
