So you put all your investments into one project, that is rough to say the least. I'm sure most have heard the phrase dont put all your eggs into one basket. If you break it, your left with nothing. Everyone should spread their investments over many projects, that way a failure wont break you.
Investing in just one coin is very risky of losses and especially in new projects, to maintain the investment value back to the initial capital, some other investments must be targeted at the top coins. Everyone has their own strategy but after learning from a lot of experience then spreading out other coin investments is a good strategy so far.
