Every investor wants to profit amidst all things. Majority of investors are attracted firstly because of the ROI after which they will now look deeply into what the project offers. For the sake of scamming, no one wants to be a victim of such so it's better to have your money and profit early and know what you are left with after after sorting out things.
If you are greedy in doing this then this will make it a risk and therefore you have to look at the background of what is happening with the coins in investment if you only see ROI so now it is not right and it is difficult to at not the price as before.
