You should always study the company in which you want to invest and I think that it is best not to choose just one company for investment, and at least a few so that even in the worst case at least one company would give you a profit.
investing in one company or in one coin. or in one ICO is never preferred. if by chance that ICO or company failed. or that coin dropped. then you'll loose all your money. so always invest in 5, 6 coins or in ICOs. so yes you are totally right in this .. at this way we can lower the risk in investing crypto a lot.
