I think we're in a slightly different type of market, the one that's maturing but also expanding by getting more and more people on-board every day. In traditional markets, the brokerage firms could easily stop offering their customers a specific type of commodity. So can crypto exchanges with coins nowadays, but most of them rarely do so. Look at Bitconnect, the damn thing was knocked down a while ago, but still has some of its market cap and even more surprising, a trading volume. So they will hardly anytime soon go to zero, but probably a lot of them will very soon have marginal significance on the market evaluation.
Bitconnect should be viewed as an example of the level of ignorance still in the cryptocurrency market and a sign of how far we are from a functioning and professional market. The very fact that people cannot or will not take the time to investigate if a coin they're investing in even has anything behind it is the reason that they will ultimately go broke and leave the crypto market. Eventually when we lose all of these such investors we will be left with mostly rational and knowledgeable investors and then currencies such as bitconnect and others with no use can go to the 0 or next to 0 value that they deserve to have.
