I still see cryptocurrency as one of the best digital investment and I totally love the technology when it comes to the largest crypto asset Bitcoin As a trader, I have been able to understand that there are two sides when it comes to crypto and everyone has their opinions when it comes to choosing sides, though i am not kicking against Hodlin, but I see it as an old and odd strategy to make profit of the market as when the market goes bearish investors/traders loses their investment which is always painful, when you can take advantage of the market by involving in day trading or copying trade alert from a professional trader that understand the market and use strategy to generate signals daily to make profit, to grow your portfolio as i have been doing with Mr Kristin crypto Expert. for the past 5 weeks and i have been able to trade to grow my initial 0.8 btc to 6.8 btc which you will rethink and see that trading is better/profitable.. Mr Kristin crypto Expert. daily signals are very accurate and always yields a great positive return on investment. -

The course is very confusing, why moving from one app to another? Why would you create an empty contract and then start another one just to make a hello world instead of adding things to the first contract?
Also, you start with Remix then just move to truffle. What's the point?
In Day2-Hello-World app many people are having problems with the callback of the hello method call and no answer has been provided.

Can anyone help me with this error I get when trying to use the bigNumber library?
TypeError: result.toNumber is not a function
TypeError: result.toNumber is not a function
TypeError: rawIds.map is not a function
TypeError: result.toNumber is not a function
Sorry if this is due to some trivial error. I am new to javascript.
