For the new project if there has many partnership with top exchange then I can consider easily for investing otherwise I won't late buy cheap price for a old top coin. At least if we have enough knowledge about crypto market then every action we can invest any time.
The only thing you could do this investment is to join their IEO where they sell some coins that have a lower price in its early stage. if it is listed on some top exchanges, the chance of the price going higher is possible. if those altcoins are listed on some top exchanges in the future. just be careful about not investing in some rubbish exchanges or you gonna regret your decision later.
