If you want to invest, I recommend you invest in bitcoin, where most of the ico is currently in a state of death. Whether bullish or bearish, bitcoin is the cryptocurrency most worth investing in.
Yeah i also like it , Bitcoins are worth investing as the whole crypto market depends on bitcoin , but there are some other alts also which can give you more profit than bitcoin in bullish market. But all icos are not dead , even in this bear market i saw some icos listed and traded in first few days with 5× ico price , but the prices eventually came down and now trading in less than ico price.
