Yes. New cryptos are born almost every day, following their lectures on YouTube, about coin A and coin B and coin C is good and worth investing in. Well, there's one thing that we didn't know until now, namely the Big Exchage Owners, Their Eyes are only focused and fixed on one thing, namely Buy and Collect as much BTC as possible and nothing else even though there are many other coins that are worthy and deserve to be taken too . That should also be a motivation for those of us here who have some reserve funds that don't interfere with our daily expenses for us to invest even in installments (DCA).
Most rich people like certain exchange owners will not see more other coins if owning Bitcoin and the coins they develop themselves are enough to make a profit in their life. Exchange owners will be more than happy to continue receiving commissions or fees from their own exchange services rather than having to buy new coins which are generally still not as good as Bitcoin.
So exchange owners won't see more coins as a good option although it wouldn't be bad if they want to be used as an additional option for investment, but as I said, that if they have had enough of investing in Bitcoin and also in coins that they develop themselves, I don't think they will be very interested in other people's coins even though the coins are already in their own exchange. And for now I still haven't found a better coin than Bitcoin, especially if it's a new coin that was born this year.
