The 2017 bull run was based on hype that was why shitcoins were able to give more profit because they were cheaper and people bought it based on the huge hype in the market then
But the next bull will be quite different from that and it will be based on real life usage and adoption so any project or altcoin that doesn't offer real usage or solve a problem will beat the dust.
Next bull run is under the question, the expectations shouldn't be high in my opinion. I wonder if there gonna be a real bull market in the next 5 years. The real-life use case depends on the ability of the professional team but only small parts achieve this success. The IEO trend can bring the next wave of the altcoin season like the HYPE of the all-time high price levels in 2017.
