I think having a few hours above some TA price level isn't enough to declare a bull market. With traditional market it's a week or more, so in Bitcoin it should be 2-3 days. Right now the price can easily go down again.
I agree that the advice is good, but I doubt that a lot of newbies will see it. From what I saw during the last bull run, a lot of noobs join when the bull run is in full swing and when the market is about to crash.
This happens all the time: newbies buy when the price peaks, and then they watch how it crashes, day by day. However, the key here is patience. People who were buying when the price was $1,132, in November 30, 2013, wouldn't regret it if they waited until 2017(especially the end of the year).
So, I think the main advice here would be: Buy only with money you can live without for 4 years, and you'll be okay, most likely.
Good advice to not over-invest. Newbies also often buy with the mindset to sell it when it doubles or triples. So, another important thing is to see your BTC holdings as a fiat generating asset. One time fiat profit should not be the end goal. You just monetize the asset in parts at your target price to cater to your needs or whatever while ensuring that you keep a significant portion purely as "BTC wealth"
In order to not fall in the same trap of servitude and consumerism, whatever level of BTC you hold, is your ticket out in the face of long term uncertainty of fiat economics.The wealthy of the world don't wrap up and sell off properties so that they can have billions as cash. They keep their wealth as long term assets that have been serving them for generations now. For people with non-fractional quantities of BTC, It has potential to serve as foundation of long-term wealth while giving fiat benefits as price increases.
