More precisely half of the capital is invested in BTC for long term portfolio, I have bad experience have invested all capital in altcoins (besides top altcoins) for the purpose of double profit but everything was not as expected and even suffered high losses. Now my investment focus is only on BTC, ETH and BNB.
I also got many experiences investing in altcoins that I've just chosen but that's okay. Because the capital that I've spent there was okay to be spent and lost because I've got my secured portfolio holding the top 3 of mine, bitcoin, Ethereum, and BnB. I'm sure that others are also hanging into these cryptos because they're the kings and at the top of the market. I'll still be fine to invest with little money just for those projects that I think got the potential but at the same time, I've learned from my experiences.
