New coin/token are at their infant stage so it won't be nice or advisable to pump your resources into it but if you are to invest, it should be for a short time with a bit of due diligence of how solid the project you want to invest in is.
In my opinion, new coin are even more able to provide a big profits and be used as a long-term investments, it's just that we really have to be prepared for the risks, because the risk of investing in new coin is very big, so before investing in new coin, we must be prepared to lose our money and really do research, because if new coin that we invest is successful, then we can get a big profit.
