I rarely invest in ICO, because I can not find worthy projects. Having studied the project Llitenett, in more detail, found it a lot of positive, especially they have a strong bounty company that is already active. You can not even invest in the project, but with the help of a bounty program to earn tokens.
There are things which can help you in having lot of earning and that investing in ICO and buying of the bitcoins are one of these things which can help you in turning all your dreams into reality. You need to look at both the options and then you need to make a choice which you think can work in a better way for you. I will go for buying of the bitcoins as this is something which I trust the most.
