So basically, you're asking a professional trader whether he really thinks trading is better than investing?
Actually, he does both: he trades frequently to get free coins that he holds as an investment. When he gets that "hot potato" feeling because the market has been very bullish, he sells off some of the profits, and keeps the rest to let them grow. If the market grows, he can sell some more. If it retracts, even better because then he gets to trade and get more free coins!
Luc has said over and over that his old videos are always valid, regardless of the overall market trends. Trade when there's an argument and panic breaks bases.
You're right that the bounces aren't as high right now, but they're still there. You just have to adjust your targets accordingly by waiting for longer drops and/or taking smaller, quicker profits. If you find it breaking too many bases at a time, you're probably not drawing your bases properly.
The problem with cryptos as a long-term investment is that they don't pay dividends. The only way to get money out of them is to sell some, which always means having fewer coins. So regardless, if you're planning to use your crypto wealth as an income stream for life, you need to come up with a long-term strategy for selling them off in a way that maximises your profits, e.g. selling enough during the peaks so that you're not forced to sell during the slumps to have living money. It's great to be "worth" a million dollars in bitcoin, but if you never ever sell them, then what good does it do you, really?
