Altcoin portfolio is more risky, but at the same time, they often grow better. But I prefer to keep a part of my portfolio in BTC and USDT, waiting for some good investment idea in short term and increasing amount of BTC. Also, I hodl EOS and BNB altcoins in long term.
I agree, it's time to invest, choosing the coins very carefully, many altcoins are too volatile and useless, you should always be ready for river jumps, so take out the main ones to the strategic reserve, they are an investment on their own, and if you calmly choose, you can invest in time and thereby increase your protection and increase the value of your portfolio.
