Catalyst you say? As of now, the only catalyst is bitcoin on an upward trend. Some say a bull run.
I remember back in 2018 when almost all altcoins that I follow kept on releasing some news every week or two in order to keep the price up. All those hype were not working because bitcoin was freefalling at that time. I don't think that has change until now. Now matter how fundamentally good an altcoin looks, its price will still depend on btc's movement.
for now it will indeed be difficult to experience an increase like the bull in late 2017, because what can trigger the price of all coins to rise is the increase in the price of BTC, so it will be difficult to do if the BTC is still stable.
