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.
This will not still trigger the bull run for the whole crypto market, but that the individual coins in separation, that are able to provide solutions to pressing problems and are able to deliver to pressing needs, will grow like what coins experienced during the last bull run.
It is also necessary that companies, firm, groups, important personalities, governments and the world, in general, to adopt cryptocurrency, before there can be general bull run, because we need more investors to come into the crypto space.
