Today in 2018 icos are still profitables, but there is a lot of people... and its getting very hard to get into the best ones. The admins even make lotteries and other things that we never saw in 2017 the golden year of whole cryptomarket.
ICOs are not as profitable just as last year, whereas you could potentially make money on majority of ICOs. Now though? You'd have to handpick them correctly. This is simply why I really don't suggest investing in ICOs right now due to the risk, not to mention the risk of potentially getting scammed.
