Buy bitcoin as much as possible if you don't have a time to do a research on ICO
because ICO invetments is risky for everyone if they don't have good knowledge about new project
ico investment must be understood. indeed a big risk behind it. we should be able to do well in choosing ico. but true as you say. buying bitcoin is a safe solution
Both of them are really good and profitable if you really know what you are doing. I suggest do your own search first how bitcoin works and how ICO works here in crypto world then ask some opinions of experts and for sure you will know the answer to this questions. It is good both instead of choosing one.
I also invest in BTC and ICO because it helps me balance my account and not lose much when one of the two investment channels is down. BTC as a reserve asset, while ICO is a form of investment that yields great returns but risks are also higher. The market is growing again and this is an opportunity for investors to choose their own good projects.
