It is a really good option, only if you know that you are not falling into any scam. Most of the ICOs now a days are scam, they loot people and then run away and there are many which starts good but are not able to reach the exchange.
I will always advice you to research well before investing.
A big suggestion try to be clever, invest certain part in Bitcoin and certain in
ICO. You will have a strong backup by Bitcoin and you can involve in ICOs as well.
