I think that now investments in Bitcoin will be more prudent than in ICO. I would invest in altcoins, they grow faster
I dont know where you find that reason because many of people knows that most of the alts in the market does not have a good future meaning over the time the value continuosly drops and does not have a chance to recover. But it is up to the investors where they can put their investment and sees the market.
If we take into account the forecasts for the near future, that Bitcoin will be able to rise to $ 10,000, and even further it may soar even higher, then it is probably better to invest in Bitcoin today than in new company ico projects.
