Why not instead of giving us out side link, you tell us the 'secret sauce'? It's pretty obvious that you are trying to promote something here in this community, and usually members doesn't like this kind of shady method. The best advise is just simply buy low, sell high, no need to make things complicated in trading cryptocurrencies.
It is obvious that they are indirectly promoting their own service and website through this post, looks like they offer crypto trading training service which is paid and they want to market that here.Yes, this community is really a big market for other services to promote their platform, but at least don't mislead crypto traders.
Regarding your comment of buy low sell high, yes it works for longterm only and perhaps suits largely to btc trading as btc is considered to move in market cycles like one bullish wave and then one bearish wave but these waves can last multiple years, so yes if you buy from bear cycle and sell during bull cycle you can make decent profit but a lot of patience is required to do it and it is more like hodler strategy not active trading.
Ok, it may not be easy as it sounds like, the 'buy low, sell high', but it is very effective specially if you are a active trader, or even a complete beginner can understand it. And then probably work his/her way around in a bearish/bullish cycle. It is also effective if you are a day trader, as the price swing will be favourable if you know how to take advantage of that philosophy.
