People who stopped chasing the next bitcoin missed out on altcoins that did over 100x return. This will happen again and some of these new projects will wildly out perform bitcoin. It is much easier to pump a low cap coin than it is to pump bitcoin.
Chasing altcoins that bask in glory for microseconds when they enter an exchange, isn't exactly my idea of "outperforming Bitcoin". Everyone starts at 0, but only bitcoin ever reached 18k. And someday it might even surpass that.
10 years later, bitcoin is still worth nearly 6000 USD. whats the closest one, BCH at 300 USD?
If you bought (or mined) bitcoins in 2010 for cents and sold them in December of 2017 for 19k, how is that inferior to an altcoin that barely reached 10 USD and then plummeted to cents for the rest of its life, with the ocasional pump making it go back to half a dollar for like 5 minutes or so?
Of course you cannot pump Bitcoin anymore, it is too costly. that is the whole point. It is going to be more and more stable with time, its working as designed.
You can still make money with altcoins, but it will never reach the legendary levels of Bitcoin. There is only 1 Bitcoin, and thousands of altcoins, of which only a few people might even remember their names.
