We are more focused on bitcoin than ever as most of the users wants to invest into bitcoin assuming a bull run post halving but nit many are planning to invest into altcoins, I think we need to focus on altcoins as well as there are coins like Tron, ADA and all which can pump anytime and priced extremely less as of now and even if bitcoin pumps it will have positive affect on altcoins as well so I think we should invest into reputed altcoins as well.
Not everyone who only invests in Bitcoin, now Altcoins have a very good potential to invest in the long term.
I think there are about 99% of investors who invest in Altcoins and Bitcoin, the rest are only a small number of investors who only invest in Bitcoin.
I also like to invest in some Altcoins because their prices are so cheap that I can buy them in huge quantities.
