You missed 2019, cause by 2020 there are only 50 coins in the market those are the projects with use cases and has a real product.
i don't really think so. 2 years is not enough time for this market to get its shit together and start having real things in it instead of shit. by 2 years we may be buried under shitcoins. in fact i expect the number of shitcoins picks up again pretty soon and we can surpass 5000 shitcoins eventually in a short time. of course they will all die but the rate of new shitcoin creation is faster than their death rate.
and this can last until 2020 and beyond until people involved in these markets start demanding something more than pump and dumps.
Sooner or later a cleanup will be done in the market and projects without a real use should fade. Competition is good but an absurd amount of tokens have been created that will deliver nothing, the hype over ico's is great, it's still going to be a while until this fever goes away.
On the topic, they are bets, I would stay away from projects that have nothing to deliver, bet on solutions for everyday use.
