Firstly, thank you for the music bonus! I'm listening to it while I type the reply... :)

Secondly, that quote looks like one of those big financial OGs, Warren Buffet, or some of his buddies... But, it is true, you allocate the most in 1-2 assets, and the rest is just "tryouts"... and not a lot of that "rest"... I had a lot of cryptos in 2018, and most of them vanished... I would be in a much better position if I was HODLing only BTC and ETH... I wanted to be a "smartass" who knows better than others or those filthy BTC maxis... :)

and regarding those "popular" YouTubers... I take them as a starting point for research... and only as that... As there is no way that they KNOW more than 5-10% about what they are talking about... Or, they are paid to shill... which is very often the case that we are not aware of.
