Thanks for the video. Watched it in full.
I think that guy has a lot of valid points but it doesn't seem that he gets the difference between crypto and Bitcoin. He also sees Bitcoin as a risk asset and gold as the safe haven.
The talk about a new form of world trade currency that is on "a Blockchain" sounds to me that that will likely be Bitcoin.
If all what he says happens, Bitcoin is likely to come out as the new world trade currency / reserve currency, which means we will be in the millions per coin.
Selling BTC at a cycle top bigly is really nice but that's only half of the gamble. if you don't get back onto the train again at the right time, you can easily lose the (generational) opportunity of your lifetime.
I think none of his arguments destroy the value proposition of Bitcoin.
If you successfully trade the cycles, great! But that's not a safe strategy for everyone. I think that would be hodling...
You won't do anything wrong by just hodling. Everything else is speculation, which relies on the past (cycles) but don't necessarily print the future.
Also, as you said, Bitcoin is different. Shitcoins are bought to be sold (for BTC?) later, while one might keep most of his Bitcoin if he/she doesn't need the money, to avoid the mistakes you mentioned.
