Holding Bitcoin now isn't such a bad idea when the dominance keeps growing. You should monitor the BTC/alts -chart and when it tops, move BTC to alts. Another way is to swing trade alts with a relatively large portfolio. Takes time but there's always one or two moving up and by swing trading and rotating within your portfolio, you can mitigate the downside while growing alt bags.

Alt season feels like a myth.. waiting for it since last year

It's coming, that's for sure. In this crypto space, you just need a lot of patience, fren! 🙂
