I like how this guy spends 2 minutes to explain how for-loop works as if I am being introduced to programing for the very first time and then latter he rapidly jumps around the entire project and multiple documentations and rapidly finishing off multiple deployment scripts and tests scripts with superficial explanation as if I am already very well familiar with blockchain development and just need a quick refresh

[@rogueninja185]

From what i ve seen this is far from a beginners course if you have no prior notions of programing language. This is just a "watch and repeat" process, not learn how to do it yourself.

starting with blockchain might be a losing strategy. learn mern, python first within 1 year and start doing some freelance tasks, then start moving into blockchain. Otherwise, you might be risking the burn-out and attrition

I don't normally comment on KZbin videos, I'm way more comfortable "listening" to the conversation but I have to tell you and the entire freeCodeCamp crew that I truly appreciate all that you are doing. I have learned more from the courses that you giveaway than I have in "academies" that I paid $7500 to enroll in. Your teaching style is awesome and I am most impressed by the way you suggest that we try to troubleshoot on our own instead of just giving us all the answers. No one can learn if you hold their hand the entire journey so THANK YOU PATRICK! This is the best decision I've made all year.

@@jayendrabhagat3607 Absolutely. The course that I paid $7500 for spent most of the time on the history of blockchain, theory and definitions, not nearly enough time on practical applications and hands-on learning. I prefer the immersive form of learning and I have that here. I don't really need 35 lessons on the history of blockchain.

We are already in the big crash, Inflation is a catastrophe. This CPI report is a colossal failure. To bring the housing market to a halt, the FED will have to pull all the stops. The unfortunate issue is that other markets are being decimated. If you want to stay green, you have to rely on a lot of diversification. Currently up 14% and being careful. Still a better deal than leaving it in a savings or checking account yielding 0-1 percent interest.

People believe their currency has the worth it does because they have no other option. Even in a hyper-inflationary environment, individuals must continue to use their hyperinflationary currency since they likely have minimal access to other currencies or gold/silver coins.

Inflation is gradually going to become part of us and due to that fact any money you keep in cash or in a low-interest account declines in value each year.

One advice that I have found useful from one of my books is the fact that if you buy stock with low p/e ratio (also called price to earnings ratio and if the is low it usually means that relative to the stock's earnings the stock is undervalued) and also with high return on invested capital (if the return is high it means you made profit) but this is not financial advice to me it is only useful.
